4. Turn the power on

Before turning on the power, insert the SD card into the Raspberry Pi combined with the Lightning Shield.

After that, supply power through USB/AC adapter/micro-B USB and turn on the power! Do not worry about the first boot, it takes about a few minutes to show the first display.

Be careful!!
If you are using an Arduino, make sure that the programs written on the Arduino do not damage the Lightning Shield(pin 0, 1, 4).
Please check your program before power on.

The first boot video can help you!

partial update

NOTE

• Syncing... means downloading the blocks.
  • It takes a lot of time and sometimes restarts.
• If ePaper displays “no IP addr”, Raspberry Pi does not get IP address from DHCP server.
  
  • It might be caused by the fail Wi-Fi setting.
• If you want to change the mode from CLIENT to AP, press Shield’s switch for more than 5 sec..
