EJ8951-4W is designed for driving Electrical Paper Display (EPD) in big sizes 31.2" and 42" with 16 grey levels support, such as EC312TT2, ED312TT2 and ED312TT3

There are two ways to drive Electrical Paper with eJump boards. One way is based on Raspberry Pi, second way is based on Windows with Zadig USB driver.

Download Demo Code for Raspberry, then follow Applications notes for Programming Raspberry Pi and setup “e-paper type” and “id” in main.cpp. The command line in Raspberry Pi is then very easy: “sudo ./main pictures playlist.txt”.
