Just noting that this is based on a previous project[1] which used a slightly less costly ($1500 vs $2300) e-ink panel: https://shopkits.eink.com/product/31-2%cb%9d-monochrome-epap...
There is also a 4096 color 31" e-ink display available: https://shopkits.eink.com/product/31-2%cb%9d-color-epaper-di... and a 42" mono display: https://shopkits.eink.com/product/42%cb%9d-monochrome-epaper...
