Introduction

Note: As the raw panel requires a driver board, we recommend you to buy the HAT or buy a driver board for use, or you need to make the driver board by yourself. And this instruction is based on the version with PCB or driver board.

FAQ

 Answer:
  • Two-color B/W e-paper
    • 【Working】Temperature: 0~50°C; Humidity: 35%~65%RH
    • 【Storage】Temperature: ≤30°C; Humidity: ≤55%RH; Max storage time: 6 months
    • 【Transport】Temperature: -25~70°C; Max transport time: 10 days
    • 【Unpack】Temperature: 20°C±5°C; Humidity: 50%RH±5%RH; Max storage time: Should be assembled in 72h
  • Three-Color e-Paper
    • 【Working】Temperature: 0~40°C; Humidity: 35%~65%RH
    • 【Storage】Temperature: ≤30°C; Humidity: ≤55%RH; Max storage time: 3 months
    • 【Transport】Temperature: -25~60°C; Max transport time: 10 days
    • 【Unpack】Temperature: 20°C±5°C; Humidity: 50%RH±5%RH; Max storage time: Should be assembled in 72h

When store three-color e-Paper, please refresh it to white, and keep the screen upward. Note that you need to update it at least every three months.
