{{FAQ|Working requirements of e-Paper?
- 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
Answer:
The I/O level of Arduino is 5V, and the e-Paper should be driven with 3V3. If your Arduino cant drive the e-Paper successfully, please try to convert the level to 3.3V
You can also try to connect the Vcc pin to the 5V of Arduino to see whether the e-Paper works, but we recommend you not to use 5V for a long time.
Answer:
You can try to change the value of Vcom on demo codes.
Answer:
Because of different batch, some of them have aberration. Store the e-Paper right side up will reduce it. And if the e-Paper didn't be refreshed for long time, it will become more and more red/yellow. Please use the demo code to refresh the e-paper for several times in this case.

Answer:
Please set the e-paper to sleep mode or disconnect it if you needn't refresh the e-paper but need to power on your development board or Raspberry Pi for long time.Otherwise, the voltage of panel keeps high and it will damage the panel
Answer:
Please make sure you have used it in correct way.
Answer:
Please set the e-Paper to sleep mode after every refresh, otherwise, the e-Paper is damaged because of working in high voltage for long time
