Description
Hive Helper - Home Assistant epaper display
In addition to the PCB and its associated parts you'll need to source the following:
- Xiao ESP32C3 (https://www.seeedstudio.com/Seeed-XIAO-ESP32C3-p-5431.html)
- WeAct 2.9" epaper B&W display (https://www.aliexpress.us/item/3256804458201128.html)
- Heat-set inserts (https://www.adafruit.com/product/4255)
- 4x 20mm m3 screws
Steps for getting started can be seen on the associated hackster.io project page for this project: https://www.hackster.io/timo614/hive-helper-xiao-esp32c3-epaper-home-assistant-display-6583fc
