# Electronics - XIAO ESP32-C3 + Waveshare Pico ePaper
|
|
|
|
## Hardware
|
|
- XIAO ESP32-C3 (RISC-V)
|
|
- Waveshare Pico ePaper 4.2 (400x300 B/W SPI, 2-color)
|
|
- Prior C driver: Gitea adolforeyna/basic1
|
|
- Target: KidsOS / Tactility stable grayscale UI
|
|
|
|
## Display Driver Preference
|
|
- Stable pseudo-grayscale: clean full black/white reset + 5 selective fast partial passes
|
|
- White stays white, intermediate black drives distributed to avoid ghosting
|
|
- Avoid harsh black / ghosting — soft pencil aesthetic similar to reMarkable
|
|
- Method: full clean -> 5x selective fast partial passes distributed
|
|
|
|
## SPI Wiring
|
|
- Verify against Waveshare wiki: BUSY, RST, DC, CS, CLK, DIN + VCC/GND
|
