RP2040 ePaper Feather 'bones' success!
We just wired up this EPD (eInk / ePaper Display) Feather and it works great! it's our "RP2040 Bones" board with standard 24-pin FPC eInk connector and support circuitry in the empty spot. with the 8 GPIO we've wired up a separate SPI port, 4 control pins, and then set up the NeoPixel to have a separate power pin so it will work better for low power usage. to be clear, the RP2040 isn't really designed for super low power usage, but every lil bit counts! we're going to send some over to tannewt next, so he can maybe test out the 7-color ACeP displays that were recently added to circuitpython…
