This weeks EYE ON NPI is a real throwback for us, it's the Orion Fans' ML2010 Mini-lab (https://www.digikey.com/en/product-highlight/o/orion-fans/ml2010-mini-lab), a portable engineering toolkit built into a suitcase for easy transport. This Mini-lab reminds us of the MIT Nerd-Kit used in digital and and analog design classes that require construction of circuit labs (http://web.mit.edu/6.111/www/project-photos/s98-projects-photos/s98projects.html). These suitcases were durable ...and super heavy! Thankfully we did not have to carry them back and forth to home each day - there were lockers in the lab. Many a digital-lab student wished we could keep the kits after finishing the course but sadly nerd-kits were not for sale - and we shudder to think what fate would befall us if we neglected to return them. Which is why this NPI caught my eye...finally I can have my very own nerd-kit thanks to Orion Fans and Knight Electronic Products. This silver suitcase contains many common analog and digital-logic tools to help prototype projects on a breadboard: Breadboard Power supplies Function generator stimulus Sweep ramp generator stimulus Pulse generator stimulus Protoboard I/O ports Switches Indicators Heavy-duty carrying case The solderless breadboarding area is made of three 630-point solderless breadboards (https://www.digikey.com/en/products/filter/solderless-breadboards/638), so large circuits with many breakout and dev board PCBs can be laid out. There's also a separate perf-board area (https://www.digikey.com/en/products/filter/prototype-boards-perforated/636?s=N4IgTCBcDaIA4FMBOAzABAIwPYEMkBMQBdAXyA) for higher-frequency work that could be affected by the breadboard capacitance, or when you want more mechanical stability. The perf-board snaps out when your project is done. The power supplies are where analog hackers are going to be happy, particularly folks who are designing exotic motor/power systems or audio/synthesizers: it has both +5, -5, +12, and -12V at 1 Amp output split supplies, and isolated-ground +18 and -18V at 1 Amp outputs, all with 0.1% line/load regulation and short circuit protection. For AC supply design - rare to find, so if you need it this will be a blessing - there's 15VAC center tapped that can supply 500mA. The power supplies are fused, and controlled by a large on/off rocker. Another great feature for analog hackers: there's also a full-featured function generator (https://www.digikey.com/en/products/filter/function-generators/630), with sine/square/triangle out - up to 18Vpp and +-10V DC offset with selectable decade ranges from 1Hz to 1MHz, and low distortion under 100KHz. There's inputs for FM, AM and sweep modulation (https://en.wikipedia.org/wiki/Modulation), for low-frequency RF experimentation. There's also a plethora of connectors and switches so you don't have to figure out how to panel mount connectors or work out mechanical stabilization. For toggle switches, there are 2x SPDT momentary toggles, 2 x SPDT toggles, and 8x logic level toggle switches. D-Sub connectors also: DE-9 and DE-25 in plug and socket format. For connecting to other test equipment, 3x BNCs. And for input/output, 8x red LEDs, a 1K pot, a 100K pot, and an 8 ohm 1/4 W speaker. The Orion Fans' Mini-lab toolkit (https://www.digikey.com/short/bdhcv3pw) would make a great resource at a lab, workshop or classroom. It's hefty and durable but that also means it'll last a long time. It's an excellent step up from just cobbling together parts that can come loose, and you can put it away safely between hacking sessions without the risk of someone 'borrowing' a part! And best of all, it's in stock right now at DigiKey for immediate shipment! Order today and you can be prototyping in style on your very own Mini-Lab by tomorrow afternoon.

The new Raspberry 5 has a new UART port, which is great because the first 4 Pi's used the hardware serial as a UART - which made debugging hard when using something like a GPS. However, unlike the GPIO header UART, this connector is SMT, and much smaller than 0.1" pitch. While we can always contact the Pi folks for a part number, let's figure out what connector it is just using a pair of calipers - then find a cable that will plug in that we can use to get that tasty RX/TX data out!

This week's EYE ON NPI will take a load off your mind, it's Nexperia's NPS4053 5.5 V Load Switch (https://www.digikey.com/en/product-highlight/n/nexperia/nps4053-5_5-v-load-switch) - it's Nexperia's first load switch and they did a great job with the NPS4053 which can be used for a variety of situations where you want to separate power supplies for protection or power savings. I'll admit, I've never used a load switch chip before - so this EYE ON NPI was a bit of a learning experience. Traditionally we've used 3 major ways to switch current. First is, of course, a simple switch - we use something like this on our QT Py Lipo BFF (https://www.adafruit.com/product/5397) where we want to allow mechanical switching and the amount of current isn't super high. The slide switch is specified for 300mA and we double-up the DPDT to allow for 600mA. This could be expanded upon with a power switch that can handle up to 240VAC and 5A (https://www.adafruit.com/product/3991) - but of course someone has to flip the switch. We could solve that issue by going with a relay or a solid-state-relay (https://blog.adafruit.com/2023/08/03/eye-on-npi-sensata-crydoms-series-1-ac-panel-mount-solid-state-relays-eyeonnpi-digikey-sensata-digikey-adafruit/) but they have some downsides as well: high cost, large space requirements. We need something much smaller! On our dev boards we have historically used two techniques for flipping on/off power to subcircuits. One is the P-FET high-side switch, which you can see on our Metro boards on the DC jack (https://www.digikey.com/short/d3j7z977). This method is classic, and works well but has a few downsides: you need a second transistor to control high voltages with a low voltage signal since the gate is pulled up to the high input voltage. Also, there's that built-in diode that is will conduct current from the output back to the input - you can see in our schematic how we also have to add a forward-diode to protect against that. Altogether, you would need 2 transistors, a diode and a couple resistors to make a FET-based switch. There's also another downside to FET switches, which is that they are not current limited, so if you happen to be switching a significant amount of current, it could cause a transitory spike on your main power supply...which causes a brownout! Something we experienced when we tried using a P-FET to switch on-off an I2C port. It worked great for low-current sensors but would crash the board when used with a 100mA-draw air quality sensor. So we used a fully separate LDO on the Feather ESP32-S2's (https://www.digikey.com/short/4nj457zb) - this works because we have a volt or more drop from the conversion from 5V to 3.3V so if there's a dip in the voltage, it isn't going to affect the main micro's power supply. This works because the LDO is only a few cents (https://www.digikey.com/short/fnr9jtnj), and we happen to have the headroom. It also has true-disconnect (no extra diode needed!) and is compatible with lower voltage logic signals. But, most devices have a DC/DC converter which is going to be a lot larger than a SOT-23-5 LDO - and there might not be as much headroom. That's where the Nexperia NPS4053 5.5 V Load Switch (https://www.digikey.com/short/ttjt5mjw) comes in! It combines all the analog electronics you need to easily switch loads of up to 5.5V at 2A, with all the niceties that you'd normally have to manage by hand. Instead of a second diode, it has true-cutoff. Instead of a separate current-limiting circuit (https://en.wikipedia.org/wiki/Crowbar_(circuit)), you can set the current limiting with a resistor and the load switch will turn from Constant Voltage to Constant Current mode. The chip also handles transients nicely, with soft-start, so that you don't get a shock to the power supply if the sub-circuit turns on all at once! In addition, there's Under Voltage Lockouts and short circuit protection. If something does go wrong, the chip will disconnect the load and drive the FAULT pin low, so you can communicate to the user that something is amiss. For many of the short/temp/over-current errors, the chip will naturally recover. With an adorable 2x2mm HVSON package and a cost of only 20 cents in quantity, the Nexperia NPS4053 5.5 V Load Switch (https://www.digikey.com/short/ttjt5mjw) will fit into the same board slot as a transistor for not much more, and replace a ton of power management circuitry with elegant simplicity!

This week, we saw an article on reducing EMI from a wireless charger using a clamp-on ferrite bead. (https://oh8hub.substack.com/p/eliminating-radio-interference-from). These clamps are great because they can be installed post-build! On DigiKey we can find them by looking in the Cable Ferrite category (https://www.digikey.com/en/products/filter/cable-ferrites/840). Let's source an inexpensive one we can use for general purpose EMI reduction, but also check out the variety of options available.

This week's EYE ON NPI surpasses all labels, it's the Brady M210 portable hand labeller - a perfect addition to any electrician, engineer, scientist, or maker who wants to keep things organized! When we first looked at this labeller we were wondering what makes the Brady device better than the Brother brand labeller we bought a few years ago - but after using it for only a few minutes we were blown away by all the excellent features that come built in. We really recommend you check out the User Manual because there's a lot of capabilities that we did not realize were included in the firmware. (https://support.bradyid.com/s/article/M210-User-Manual-and-Quick-Start-Guide) Here's a run down of some of the things it can do that you will not get with other labellers. Internationalization: Support for multiple languages with fonts and accents to match, for this labeller, the languages are all 'Romantic' and of course many Greek symbols are included. There is a separate Russian product if you need Cyrillic. Symbols: Our home labeller has cute symbols like crafting symbols and clouds - this labeller goes straight for safety symbols such as "you will be electrocuted" or "this is poisonous" or "do not look at with remaining eye" (https://observatory.db.erau.edu/generators/signs/) But also electrical symbols, telecom and home electric. Barcodes and 2D Encodings: Barcodes in CODE39 (https://en.wikipedia.org/wiki/Code_39) and CODE128 (https://en.wikipedia.org/wiki/Code_128) format as well as 2D encodings such as Datamatrix or QR code (https://www.gs1.org/standards/barcodes/2d). Perfect for when you want to include a URL or serial number that is longer than the print label allows. Serialization: printing multiple labels with a start and end value, and custom incrementation, it can even handle alphanumeric serials! Date Stamping / Coding: by setting the date and time on-device, you can insert timestamps based on when it prints. You can format the time and date for 12H/24H, with or without seconds, and different MMDDYY ordering. (https://en.wikipedia.org/wiki/Date_format_by_country) Panel and Terminal Blocks: particularly nice for electricians, you can print out labels that are perfectly spaced for breaker panels, or terminal blocks. In general we noticed that this labeller has a strong sense of spacing so that you can have multiple words or numbers and there's likely a mode that will make them center-equidistant...something that is really annoying to try to do with an everyday labeller. Wire Marking: This one is going to be one of our top uses! For complex wire harnesses, being able to label the wires so it isn't just color you're using to identify functions is amazing. There's a few ways to mark wires (https://www.bradyid.com/resources/guides/how-to-select-a-wire-marker). The easiest is Flag mode, where it will print the text twice with a gap in the middle so you can make a little flag that wraps around the wire. You can use any label size or color to make flags. For less intrusive labelling, you wrap the label around the wire. And coolest by far is the 'PermaSleeve' (https://www.digikey.com/en/products/detail/brady-corporation/M21-125-C-342/11585771) where you can print directly onto heatshrink tubing! Once you have a Brady M210 Label printer (https://www.digikey.com/short/mj7t5fwp) or printer kit (https://www.digikey.com/short/tzjqtm9r) you will use it every day to track and manage your tools and inventory. It's way better than sharpie marker'ing, or sticky notes, with a massive range of different label styles, sizes and colors (https://www.digikey.com/short/77qcpzc5) - all in stock right now for immediate shipment from DigiKey! Pick up an assortment to keep in your lab -- and of course first step is to label the labeller itself so nobody tries sneaking off with it -- when you order today it will ship immediately so you can start labelling everything by tomorrow afternoon.

This week on the Great Search, we've had our eyes on the new Pi 5 announcement - they're not shipping yet but we did get some tantalizing new images including a new PCIe connector on board. PCIe is a high speed bus that will make it a lot easier to add hardware to a Pi computer, including storage cards, cell modules, radios, and co-processors (https://en.wikipedia.org/wiki/PCI_Express) that can use 1 lane of data. A PCIe HAT is expected from Raspberry Pi at some point, and there's a few folks trying to make adapters for M.2, which we covered on The Great Search earlier (https://blog.adafruit.com/2020/10/27/the-great-search-m-2-e-key-connectors-thegreatsearch-digikey-digikey-adafruit/) So this time around let's look for PCIe sockets. We'll try to find one that is SMT and vertical, so a wide variety of cards can be inserted.

This week's EYE ON NPI stands alone as a fantastic new solution for high power charging of large battery packs and also power boosting from battery to system: it's ADI/Maxim's MAX77789 Standalone 3.15A Charger (https://www.digikey.com/en/product-highlight/a/analog-devices/max77789-standalone-3-15a-charger), an all-in-one power management IC that lets you ditch DC power plugs and simplifies your BOM, at an excellent price. We'll also be covering the MAX77787 (https://www.digikey.com/short/wzv7095b) which is the fraternal-twin-sister product: using I2C instead of resistor settings for configuration. We've been covering USB Type C PD sinks and supplies for about a year here on EYE ON NPI & The Great Search, they're an excellent way to ditch those DC barrel jack power supplies (https://learn.adafruit.com/usb-pd-hacks/) and allow folks to use a single connector and standard power supply (https://www.youtube.com/watch?v=C90UnNAlCFQ) for various voltages, from 5V-20V at up to 5A. There's plenty of chips that will connect to a PD source and negotiate that voltage for you (https://www.youtube.com/watch?v=yQea9IEmf28) but now we can start to take advantage of USB PD for battery charging as well! This week's dynamic duo does pretty much everything for battery management. As devices get more complex, and battery cost goes down, the packs included in products are getting bigger. If you're trying to charge a 5Ah battery at standard 5V/1A rates, it will take at least 5-8 hours to do so, when folks really want 1-2 hour charge rates. The MAX77789 and MAX77787 have a buck converter that will deliver up to 3A to the battery for 3x faster charging. But, if you try to draw 3A from a USB 5V power cable, that built-in resistance will cause a voltage droop - remember we need at least 4.5V to have the headroom for charging up to 4.2V or 4.35V Lithium batteries. Thus, these chips use USB PD (https://learn.adafruit.com/understanding-usb-type-c-cable-types-pitfalls-and-more) to request higher voltages when available: 9V or 12V means that we can draw less current to get the same amount of power, which means less resistance loss over the cabling. For pre-C chargers, such as Samsung or Apple or Quick Charge (https://learn.adafruit.com/understanding-usb-type-c-cable-types-pitfalls-and-more) the USB D+/D- pins are used. In such cases where you want to have the data pins available for USB data/sync, you'll need something like the MAX20334 (https://www.digikey.com/short/p8b23vf3) data line switch to flip the pins back to your MCU. The MAX77789 uses resistors on the IFAST, ISET and INLIM lines to set the charge rate, timeout, and pack float voltage, the MAX77787 uses I2C. Both have a couple configuration pins, and LEDs for status monitoring. Both have the ability to also be turned into a boost converter - you can't use both charging and boosting at the same time, but since you can use the SYS voltage when connected to USB, you'll have at least 5V either way. The booster is fixed to 5.1V output. On the '89 the boost is enabled by GPIO, the '87 enables it over I2C. Both chips are available in 0.4mm pitch BGA - which means pad-in-via and multi-layer boards in order to pass the inner configuration traces out. Many of the traces are tripled-or-quadrupled to provide the current carrying capability of 3A charge and 6A peak discharge. An eval board is also available (https://www.digikey.com/short/4dc80hwz) which makes quick verification easy. For the I2C configuration version there's also desktop software to try out various settings - the standalone version has jumpers so you can attach any resistor value. Both the ADI/Maxim MAX77789 (https://www.digikey.com/short/j7zhtj4h) and MAX77787 (https://www.digikey.com/short/wzv7095b) Standalone/I2C 3.15A Chargers are in stock right now at DigiKey for immediate shipment. It's great to see forward momentum in chip design releases now that the shortages have abated: only a year ago we were scrambling for diodes and op-amps and now we have a wealth of great new products to choose from! Order one of these powerful Lithium battery management chips today and you'll have it shipped immediately so that you can start integrating it into your new design by tomorrow afternoon.

As we are plowing through the last of our chip-shortage-recovery revisions, next up we're about to do a bunch of Raspberry Pi HAT displays. HATs (https://www.raspberrypi.com/news/introducing-raspberry-pi-hats/) are 9 years old, and are a standardized way of Attaching Hardware on Top of RPi's. Given the RPi shortage is also over, thankfully, it's time to look at more HATs! One feature that HATs have is an onboard EEPROM that helps identify the board via a set of extra I2C pins - this EEPROM can be used to load device tree fragments, contain MAC addresses, calibration details or other non-secured unique data. We've covered 25Q series SPI Flash memory before, and 24-series looks soooo similar but they are not! Let's look at some options for adding generic 32Kbit / 4 KByte I2C EEPROMs including some things to watch out for so you don't make mistakes we have.
