This week's EYE ON NPI is a big time upgrade - we're featuring GAPTEC's LC78 series switching regulator modules (https://www.digikey.com/en/product-highlight/g/gaptec/lc78_3-0-series-switching-regulator) with up to 28V inputs, 95% efficiency and 3 Amp outputs! There's two things we dig about these modules. One, they are pin-compatible with 78xx regulators that we all grew up on. So you can use them to quickly update existing designs from linear to switching power supply. Second, they are extremely easy to use, with ultra-wide input voltage ranges, various output voltages and current outputs if needed. (https://www.digikey.com/en/products/filter/dc-dc-converters/922?s=N4IgTCBcDaIOYEMAOAXApgYwAQBsMHYAOEAXQF8g) Why use these instead of just DIYing a switching regulator layout? After all, we've covered many great DC/DC controllers on EYE on NPI! Well, to start - laying out and specifying switching regulators is a real pain for folks who are not experienced with some of the pitfalls and it's very very easy to make a mistake that can smash your regulator or have noisy output or have less efficiency/output than expected. For some high current outputs, you may need to update to 2 oz copper, 4 layer boards, or have heat sinking vias. (https://www.electronicdesign.com/power-management/power-delivery/whitepaper/21120734/minimizing-powersupply-voltage-drop-on-pcbs) If your board is large enough, making the whole thing 4 layer or 2 oz just for the regulator outweighs the cost savings of DIY. And of course, it's adorable that these li'l DC/DC bricks are pin-and-size compatible with the standard 78xx regulators that have been used since the beginning of time. (https://www.digikey.com/en/products/detail/stmicroelectronics/L7805ACV/585962) That makes them a good choice when repairing or upgrading existing designs. The GAPTECH LC78's have much much better efficiency, allowing folks to use a wide range of voltages without worrying about heatsinking or air flow. (https://www.digikey.com/en/articles/heat-sinks-a-step-by-step-guide) I'm a huge fan of these kinds of upgrade modules, because they solve a problem neatly and easily. These have a massive 3 Amp output, a non-trivial amount of current to manage with a linear or DIY switching setup. At that current range these could work great for robotics, large quantities of LEDs, running single-board computers, etc. all in a compact module. These are available in both 5V LC78_05-3.0 (https://www.digikey.com/en/products/detail/gaptec-electronic/LC78_05-3.0/13692361) and 3.3V outputs LC78_03-3.0 (https://www.digikey.com/en/products/detail/gaptec-electronic/LC78_03-3.0/13692290) for immediate ordering. Order the GAPTECH LC78 series modules today,(https://www.digikey.com/en/products/filter/dc-dc-converters/922?s=N4IgTCBcDaIOYEMAOAXApgYwAQBsMHYAOEAXQF8g) and you could have your power supply up and running by tomorrow morning!

Woo it is sweltering, which means we got to stay in and do a bunch of engineering. This week we spent a little time finishing up some languishing boards - Stemma QT version of the SCD40/SCD41 and IS31FL3741 chips - we wrote libraries for both as well! We also are dealing with a massive SAMD51 shortage by redesigning some recent boards like the Matrix Portal to be S2 only (so at least there's only one chip to source!)

This week's EYE ON NPI can handle the pressure of being featured - it's the ICP-10111 Barometric Pressure Sensor (https://www.digikey.com/en/product-highlight/i/invensense/icp-10111-barometric-pressure-sensor) with astonishing accuracy that makes it excellent to use as an altimeter. According to TDK, this "pressure sensor can measure pressure differences with an accuracy of ±1 Pa, an accuracy enabling altitude measurement differentials as small as 8.5 cm, less than the height of a single stair step." 1 Pa is really good and competitive in the market . Even though we call this an altimeter, its technically a pressure sensor that uses the changes in pressure over altitude to compute. Earth's ambient barometric pressure changes with altitude - because air gets thinner the higher you go. (https://en.wikipedia.org/wiki/Atmospheric_pressure) There's a simple calculation that can be used to determine relative altitude changes and, if you know the sea level pressure (which usually doesn't vary much) you can use that to determine the absolute altitude. The better and more accurate your pressure readings, the better your altitude calculation output. GPS can also be used to calculate absolute altitude, by measuring timing differences from 3 or 4 orbiting satellites. (https://www.gps.gov/systems/gps/performance/accuracy/) However, GPS only has an accuracy of about 10 meters, which is good for large equipment like planes but not good for humans, who are only about 2 meters tall. Also, of course, you need to have GPS fix which consumes a lot of power and requires one to be outdoors. Often times, even if a system does have GPS, a pressure-sensing altimeter will be included in the system. Also, pressure sensors can of course be used underground or underwater - try getting a GPS fix there! This isn't a new kind of sensor - we've stocked a wide range of barometric sensors over the years such as the popular BMPxxx (https://www.digikey.com/en/products/detail/adafruit-industries-llc/2651/5604371) and the DPS310 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4494/11569124). But this one seems to have improved the precision, with an impressive 1 Pascals at around sea level instead of the common 2 or 3 Pascals. This apparently can give you ~10 cm differential measurements. Note that this is differential not absolute - you can tell if you've gone up or down and by how much, but it doesn't necessarily translate to precision absolute measurements (which is a different specification). One nice improvement over most sensors we've seen is that these come in four packaging options: physical size/pinout variations in 2x2mm and 2x2.5mm and then waterproofed to 1.5m depth versions with three micro-laser-drilled holes in the top. Obviously the PCB that the sensor attaches to may not be easily waterproofed, but this sensor could have a gasket covering it, or it could just be less sensitive to ingress moisture and dust. Another big deal is...all four ICP-10111 versions in stock at Digi-Key! (https://www.digikey.com/short/r248d9n8) Right now most of the other sensors we like to use are totally unavailable due to parts shortages, but you can get some of these sensors and they seem to be I2C-usage pin-compatible with the BMP280/DPS310 and BME390. Note the SPI pins are NC/reserved so its not purely pin-compatible, and of course there's some firmware updates you'll need to code up. So if you need a altimeter, and want one with waterproof casing, these could be an easy swap into an existing design to upgrade it! Order today an you could have them in hand by tomorrow morning.

The Adafruit crew will host the Hack Chat on Wednesday, July 21 at noon Pacific / 3pm EDT https://hackaday.io/event/180454-python-your-keyboard-hack-chat-with-adafruit Especially over the last year and a half, most of us have gotten the feeling that there's little distinction between our computers and ourselves. We seem welded together, inseparable even, attached as we are day and night to our machines as work life and home life blend into one gray, featureless landscape where time passes unmarked except by the accumulation of food wrappers and drink cans around our work areas. Or maybe it just seems that way. Regardless, there actually is a fine line between machine and operator, and in most instances it's that electromechanical accessory that we all love to hate: the keyboard. If you buy off the shelf, it's never quite right -- too clicky, not clicky enough, wrong spacing, bad ergonomics, or just plain ugly design. The only real way around these limitations is to join the DIY keyboard crowd and roll your own, specifically customized to your fingers and your needs -- at least until you realize that it's not quite perfect, and need to modify it again. Hitting this moving target is often as much a software problem as it is a hardware issue, but as is increasingly the case these days, Python is ready to help. To go into depth on how Python can be leveraged for the custom keyboard builder, our good friends at Adafruit, including Limor "Ladyada" Fried, Phillip Torrone, Dan Halbert, Kattni Rembor, and Scott Shawcroft will stop by the Hack Chat. We suspect they'll have some cool stuff to show off, in addition to sharing their tips and tricks for making DIY keyboards just right. If you're building custom keebs, or even if you're just "keyboard curious", you won't want to miss this one. #adafruit #hackaday #hackchat

We got a request on discord from someone with a 3D printer that needed new fans. In particular, they want a quieter fan, and one that can run directly on 24V without needing a regulator (e.g. a 12V fan). Let's visit the massive collection of fans over on Digi-Key and show how we can pare down the selection, then sort by specifications to get some great options to try. https://www.digikey.com/short/whqf0vmp #TheGreatSearch #DigiKey #adafruit 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/ -----------------------------------------

This week's EYE ON NPI can handles whatever the weather throws at it - with the Stewart IP67 Rated USB Type-A Cable Assemblies (https://www.digikey.com/en/product-highlight/s/stewart-connector/ip67-rated-usb-type-a-cable-assemblies). I absolutely adore using common, off-the-shelf connectors and hardware - like a Raspberry Pi or Arduino - for hardware designs. But, of course, most hardware you buy is not weather-proofed by default because it's expensive and restrictive. So instead, often times the final integration step is where durability is added by the designers. That's where these cables come in. Instead of re-designing or re-building your existing cable connectors to use specialized weatherproof contacts, here we are supporting the common USB type A cables that are used everywhere for connecting accessories to your single-board computer. Now you can tuck away the Raspberry Pi or BeagleBone you've got in any enclosure you fancy. The Stewart IP67 cables come in a few different flavors, so you'll want to mix and match the right kinds to get the ends and threading right. For example, there's USB 2 (https://www.digikey.com/en/products/detail/stewart-connector/67U2AC-006-K/14300409) and USB 3 (https://www.digikey.com/en/products/detail/stewart-connector/67U3AA-006-K/14300411), USB Type A plug (https://www.digikey.com/en/products/detail/stewart-connector/67U2AD-006-K/14300402) and Type A socket (https://www.digikey.com/en/products/detail/stewart-connector/67U2BD-006-K/14300407), and you can get them with cut ends or connector ends. These cables come with an environmental rating (e.g. weather/waterproofing rating) so you know exactly what kind of use cases they are safe for - otherwise known as an IP rating (https://www.iec.ch/ip-ratings) IP67 means that the connector, once properly installed is completely dust-tight (that's the 6, maximum rating possible) and protected against rain, jets of water, and even temporary water immersion. That's the 7 part in IP67. It's not meant for being dunked in water for extended periods of time - like in a pool or aquarium - you'll need IP68 for that. Of course, the higher the rating the more expensive the connectors. Compare the rating to every day electronics which naturally have an IP rating of maybe IP30, with only the most basic dust prevention and no water protection. Check out all the Stewart IP67 USB cable assemblies (https://www.digikey.com/en/product-highlight/s/stewart-connector/ip67-rated-usb-type-a-cable-assemblies) to make your own plug-and-play secure USB system with all off-the shelf hardware - it'll make weatherproofing your design easy! And they're all in stock right now at Digi-Key for immediate shipment (https://www.digikey.com/short/7r5t1m7d) - order today and you'll be ready to ruggedize by tomorrow morning.
