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.

{{FAQ|2. Why does the color of e-Paper look a little black or grey?|
 
You can try to change the value of Vcom on demo codes.

{{FAQ|3. Three-color e-paper looks more red/yellow than the picture on website?|
 
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.

{{FAQ|3. Why my e-paper has ghosting problem after working for some days|
 
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:
  • 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.
