Description

An E-ink module is great, how about to make it even nicer? Here we go! Instead of using SPI protocol, we created this I2C E-ink display to join our Qwiic family. So you can just daisy chain this E-ink display just like the other Qwiic modules!

Nothing fancy here, we add a STM32 as the gateway, it can communicate with I2C system, then drive E-ink display to refresh content by SPI protocol.

In order to inherit the ultra low power consuming feature of the E-ink display, we let the STM32 IC go into deep sleep mode (2uA power consuming) and add an I2C chip that is used for waking STM32 up. Learn more about the schematic here.

We’ve published the code for STM32, and very nicely, you can re-program STM32 by using the female header. Learn more here!
