Nice hardware, no documentation
For Pi Pico RP2040 1.28-inch TFT display watch board
A watch built around the Raspberry Pi RP2040 microcontroller. Comes with pre-blown firmware, but *no* documentation at all. The display is a GC9A01, which means it's driveable via SPI from both CircuitPython and MicroPython. The on-board IMU is a QMIC88658, and there are three user-addressable buttons — in addition to a BOOTSEL button and a on/off switch. One of these three buttons just seems to crash MicroPython for me when pushed, I may have a defective unit, or this could be a design problem for the board. Everything else works nicely. We wrote it up for the Raspberry Pi blog, https://www.raspberrypi.com/news/how-to-build-your-own-raspberry-pi-watch/.
