1 × ESP8266 board Optionally ESP32 but not needed in v1.0
1 × E-ink display with Hat exposing SPI interface Any size you like. Waveshare has nice ones like 800*480 pixels. We prefer b/w without any colours since it refreshes faster
1 × Powerbank at least 10000 ma Even if it's 5000 mA will last for long days. I'm tired of adding Lion power and charging circuits like adafruit that proved so far to be non efficient
1 × 3D Printed case and HAT cover STLs/OBJ Provided in files
1 × *optional 12x12 mm push reset button Goes between RST in the board and ground, simply restarts it
