- 1 with satri360 AIO and his 160x128 OLED and a small extra module to stick to it to do external charging
- 1 with satri360's button PCB and a great 240x240 LCD but not much else in there. This one will get the expansion header once our electronics guy can solder them for me under a microscope. It also needs a new case (messed up the back) and a case for its charging/boost module.
So, why not use an ESP32 ? I got a nice almost AIO here (smaller than the zero and including lipo charger, 4MB Flash).
Software is going to be interesting. There is a nice SDK open source from the PocketSprite which includes some fancy features like a file system and WLAN file upload. Thats not going to fully work on this 4MB board but worth looking into.
Then there is at least the nespresso build for the ESP32 which has the display driver built in. As far as I can see its not going to be hard to modify that to run the ST7789V.
