Universal ePaper Driver Shield (B) for Arduino

This E-Paper raw driver shield is equipped with an onboard voltage translator making it compatible with both 3.3V and 5V microcontrollers. It includes an onboard MX25R6435F Flash chip for data storage and management.

Additionally, it features reserved external RAM soldering pads, providing the option to expand memory space as needed for more complex projects. This driver shield is an ideal choice for people using e-paper displays in their projects, as it offers flexibility and ease of use. The shield connects with a variety of host boards including nRF528xx, UNO, Leonardo, NUCLEO, and XNUCLEO through standard Arduino connectivity.

Note: The board and e-paper screen are NOT included
