I started doing some research on a e-paper display for the keys of the macropad and landed on the 0.97 inch Small E ink Screen from GooDisplay which I will be using. I started modeling the keys around the screen and started working on the PCB : I traced all the connections for the displays and power management. I will also be using a 74HC154 to be able to select one display at a time to change its image. This project will work with an esp32-s3 with flash memory to remember each key and image and I am planning to include a rotary encoder to switch between layers for the keys
