I finally got around to assembling my ESP32 Feather-compatible board. (A few days after Adafruit released theirs. Didn’t know they had one coming) Booted straight into Espruino, connected to wifi, toggled pins. Very cool having it work first try!
Espruino is awesome and here’s a way to help fund it!
A bit unfortunate that I’ve got a stack of Wi-Fi HATs for the zero already, but I’m definitely happier to have this option. Should be good.
Cool product! I was actually looking for something like this a while ago, good to have a source now.
Just saw this on Hackaday, very nice technique for driving LEDs. I can’t believe we haven’t seen it before. It uses tricks with voltage drops to drive n²+2 LEDs with n pins, instead of the n²-2 that charlieplexing yields or the n of one-to-one connections.
I only soldered the basics into these. Given that most projects won’t need all the extras (Usb, Lipo, reset button, some of the passives), I can make some really cheap boards by only using what I need. I’ll still use fully populated boards that I’ve built or bought for prototyping, but I’ll be able to stick <$10 sensors everywhere as well.
The one on the left is my AtMega328 + RS485 interface. The one on the right is the Adafruit Huzzah board.
