On yet another stemma sunday, we're revising our ancient HT16K33 LED backpacks to include QT connectors - we're also going to try to 'unify' two or three of the layouts so they can share the same PCBs. We're also interested in redoing some of our microphone breakouts so they're easier to use in a classic stemma breakout shape. We put together both electret and MEMS versions The Great Search - MEMS analog microphone https://www.digikey.com/short/d2w32b4d We're now used to parts being unavailable, and when designing a new board we noticed the MEMS microphone we've used before, SPW2430, is NRND.

This week's EYE ON NPI is from our best buds at Bud Industries - the Bud AIO Series Enclosure with Cover Window (https://www.digikey.com/en/product-highlight/b/bud-industries/aio-series-enclosure) is a very nice case that is a step above most durable wall-mounted enclosures. In particular, what is really nice about this design is there are two 'doors' - one is the main enclosure latching door that lets you stuff a whole bunch of electronics inside. There's also a secondary clear panel door on the front, which is also latching (although not with metal hasps). Both are gasketed for weatherproof-ness. Obviously, the front door is designed for showing TFTs, LEDs, gauges or other indicators with a protected cover. However, we like the extra step of being able to open the cover to push buttons, tweak knobs or maybe interact with a touch screen without opening up the whole box which could expose the electronic design to dust or dampness. Bud's great with their documentation (https://www.budind.com/wp-content/uploads/2020/12/hbaio11111.pdf) - and the two AIO series enclosures come with datasheets that have nice diagrams of all internal and external dimensions in inches and millimeters. There's lots of mounting holes/bosses on the inside for attaching a PCB or substrate - the holes are threaded and the enclosure comes with plenty of mounting screws. The enclosure is made of ABS plastic, which makes it very easy to drill and cut. (https://www.google.com/search?channel=nus5&client=firefox-b-1-d&q=abs+plastic+machining) There's a removable plate that sits between the inner and outer section, which means it's easy to remove for machining. If you need a lot of custom panels, it may also be possible to just cut out plastic/metal/wood on a router with the drill holes and slots you need. There's also internal panels you can purchase that fit inside the case with lots of holes for quick mounting (https://www.digikey.com/en/products/detail/bud-industries/PTX-10140/13907429) Another nice detail we noticed in our exploration is the gasket material is extruded and molded to the enclosure, rather than a simple o-ring or rubber bead. That's what gives it the nice IP66 rating (https://en.wikipedia.org/wiki/IP_Code) for dust-proof and waterjet-proofness. That said, because it's non-stabilized ABS, it isn't well suited for any long-term outdoor mounting as it can degrade under sunlight. It could be used outdoors as long as it isn't exposed to sunlight too much, but it's really designed for durable indoor use. IP66-rated enclosures are dust-tight and provide a strong level of indoor-outdoor protection. Boxes that qualify for this rating will prevent ingress of water directed at high pressure. Typically IP66 waterproof enclosures are used in washdown and outdoor applications, such as factories, rooftops, solar installations, and agricultural settings. They give maximum protection against pressure-washing and weather short of water immersion. https://www.budind.com/nema-ip-rated-boxes-ip-66 There's two versions of this enclosure with different depths: the Bud AIO-11111 (https://www.digikey.com/en/products/detail/bud-industries/AIO-11111/13907415) and the Bud AIO-11112 (https://www.digikey.com/en/products/detail/bud-industries/AIO-11112/13907416), the '11111 is 9.5" deep, the '11112 is 7.7" deep. Both are in stock right now for immediate shipment from Digi-Key! (https://www.digikey.com/short/4zznn9h3) Order today and you can have a cozy enclosure for your product or project by tomorrow morning. See on Digi-Key at https://www.digikey.com/short/4zznn9h3

A die-hard interface chip that is the backbone of many-a-devboard is the USB-to-UART adapter chip. While many micros come with native USB, there is still a large number that have UART only - like the ESP32, or RISC-V cores.

OK we finally spent a few hours and finished up our UPDI stand-alone programming code. That means we can start releasing some ATtiny8xx designs because we will be able to program/test them nice and fast. First up is a basic breakout with QT connectors.

This week's EYE ON NPI is going to keep you safe and sound, it's onsemi's portfolio of eFuses (https://www.digikey.com/en/product-highlight/o/on-semi/efuse-porfolio) - chips that can perform many of the protective functions we build into our power supplies to keep devices from going poof when accidents occur! onsemi has developed a wide range of eFuses ranging from 3 V to 12 V, supporting a continuous current from 1 A to 12 A. The integrated overcurrent, overtemperature, overvoltage, and inrush current protection, along with the ability to report faults and disable the output through GPIO, make these devices suitable for protecting any system, helping meet the challenges and supporting a compact board layout. When people first meet fuses, they usually see and think of classic 'wire' fuses (https://www.digikey.com/en/products/detail/bel-fuse-inc/5ST-200-R/1009012) with ceramic or glass or thermoplastic bodies, and a thin wire inside. When too much current goes through the fuse wire, it gets hotter and hotter and eventually melts, cutting off the load from the source voltage. Pros: super cheap, easy to find, lots of suppliers with various current limits Cons: only good for overcurrent, one-shot usage only! Once engineers start making products, they often want to include fuses to protect their circuitry: over-current usually means something is getting damaged and we want to keep away from thermal damage like charring or even a fire. Many traditional/older designs use glass fuses, like appliances, radios, kitchen tools...but a lot of engineers prefer going with 'poly fuses' - fuses that are easy to mount into a circuit that auto-reset after a time (usually minutes) so that a temporary overload doesn't make the device a brick so quickly. For example, we have a 500mA hold / 1000mA trip polyfuse (https://www.digikey.com/en/products/detail/bel-fuse-inc/0ZCJ0050FF2G/4156133) on the Metro 328 board design (https://www.adafruit.com/product/2488), usually it kicks in when people try to power 4 servos off of the USB port, quickly overwhelming the computer or hub. Poly-fuses are a great step-up from plain wire fuses. Pros: also cheap! lots of suppliers with various current limits. auto-resets after cooling down. Cons: only good for over-current, can't latch off, fuse trip time depends on ambient temperature But circuit protection usually needs more than just over-current checks. We often have to do polarity protection (in case the battery or wall adapter is put in backwards), and over-voltage (to avoid damaging the regulator, which will have some voltage limitation) and under-voltage (to avoid weird or inconsistent behavior during a brown-out). There's also some products that benefit from 'latch off' behavior - where a failure means we have to do a hard power cycle. What if we could do all this in one chip? No surprise, that's what we're showing off this week! The NIS5420 eFuse is a cost effective, resettable fuse which can greatly enhance the reliability of a hard drive or other circuit from both catastrophic and shutdown failures. It is designed to buffer the load device from excessive input voltage which can damage sensitive circuits. It also includes an overvoltage clamp circuit that limits the output voltage during transients but does not shut the unit down, thereby allowing the load circuit to continue operation. Integrated Power Device Power Device Thermally Protected No External Current Shunt Required 8 V to 18 V Input Range 39 mOhm Typical Internal Charge Pump Internal Undervoltage Lockout Circuit Internal Overvoltage Clamp These chips do it all. Obviously they've got the current limiting setup, but they also have under-voltage locking, over-voltage clamping for short bursts of high voltage, slew rate control, enable / fault pin, and optional external current monitoring. It's all analog electronics so it works instantly, reliably and without digital configuration. Stuff like the current limit and slew rate is set with external passive components. It looks like these were designed for use in hard drives, which means they are good in stressful environments like server racks, data centers or home computers. We always love chips that do something and do it real well, at a good price. These eFuses will replace a chunk of your power-supply protection kit, saving your assembly cost and board size. While we're specifically featuring the onsemi NIS5420 (https://www.digikey.com/short/nt2zhct2) here, there's a whole family of different voltage-set chips to pick from (https://www.digikey.com/en/product-highlight/o/on-semi/efuse-porfolio) for 3V, 5V, 12V or even 24V power rails. And best of all, they're in stock right now for immediate shipping from Digi-Key! Order now and you can start designing into your product line tomorrow morning.

OK we're about ready to fabricate these LED glasses panels. Lots of LEDs, in a cool grid/circular design! Of course, we have to test each board so that we know all the LEDs were placed properly. Thus, the tester! We're going with a simple R/G/B test, with visual inspection. We'll also check out the built in test-mode the IS31FL3741 has, so we verify all the RGBs two ways. Check out the fancy silkscreen, we'll have these in the shop sooooooon. #comingsoon #adafruit #ledglasses Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

We use the AON7401 in a LOT of our designs, it's a high-current power P-FET that we use for polarity-verification / voltage-switching. For example, in our RGB Matrix FeatherWing, it's used to make sure we have a positive voltage going from the DC jack to the RGB Matrix. Sadly this exact part is discontinued. Let's try to find a drop-in replacement with as-good-or-better specifications!

We're always looking for more I2C-friendly displays to add to our line-up. This is a 128x128 monochrome OLED breakout we just put together, with SH1107 driver. It's a smol 1.12" inches and has both I2C and SPI interfaces. Use I2C when you want quick wiring, use SPI when you want fast speed. Either way, its crisp & clear and we'll have Arduino & Python code.

We have just a few I2C boards left to turn into STEMMA QT versions. Lets take a trip through converting a design from one of our classic layouts to STEMMA QT. The Great Search - Replacement for AON7401 8-DFN Power P-Channel FET https://www.digikey.com/short/59fpdtm1 We use the AON7401 in a LOT of our designs, its a high-current power P-FET that we use for polarity-verification / voltage-switching. For example, in our RGB Matrix FeatherWing, its used to make sure we have a positive voltage going from the DC jack to the RGB Matrix. Sadly this exact part is discontinued.
