Desk of Ladyada - Happy Arduino Day (weekend)! Arduino for RP2040, some STEMMA QT designs, and more…
130It was Arduino Day yesterday, check out Arduino's YouTube channel for recorded streams. We tried out an Arduino board support package for the RP2040/Pico with success! We got the Feather RP2040 and our QT Py both up and running with some demos. NeoKey designs are starting to make it into the shop. We sketched up a possible new Trinkey design and a breakout for a fancy new CO2 sensor. On the QT front, we're going back and QTifying some older designs still. This week we redid our old 7-segment breakouts - ancient stuff! We also spent a lot of time snagging components so we can keep in production for the next 6 months plus.
The Great Search - Replacement for APX803 Auto-Reset Supervisor
https://www.digikey.com/short/r07ph903
Much like the post-recession months after 2008, we're in the midst of a bit of a component squeeze. Chances are you've been warned by your suppliers that many parts are in short supply, and lead times have stretched into the many-months or even a year! Here at The Great Search we feel ya, we've seen many components evaporate. Parts that were discontinued-but-still-available are now 'really really discontinued' But no worries, with a little search-skills we're often able to find replacements. So it's no surprise we'll be doing a few 'alternative' search shows! This week we're going on the hunt for a replacement to the APX803-26SAG, our favorite auto-reset supervisor - a little chip that has helped countless designs wake up cleanly. It's no longer available, will we be able to find a drop-in replacement? Tune in to find out!
