Hi
I have a EInk feather 2.13 mono
and i manage to get it to display stuff if i use a 5v power in the 3v pin 2:na in from the card-slot.
and use memory from the processor board.
since the memory does not seem to work on 5v
if i go down to 3.3v on that pin, then i can via SPI send a string to the memory and then read it back so memory seems to be working on ~3v (this fails at 5v)
but then the display will not draw BANNED.
I use it from a Esp32s3 dev kit.
any thoughts on how to get this running with both the memory and display or is there something wrong with my board.

Re: EInk feather 2.13 mono
FeatherWings are designed to be used with Feather main boards. Use with non-Feather boards is generally not supported. It may be possible, but you'll need to use the available pinout and other information for the FeatherWing to determine the proper connections.

Re: EInk feather 2.13 mono
the pinout for the feather board that is on the site is abit short on details
but by the images and i can find the 3v gnd and spi pins and all the select and dc is marked on the board.
i stateted to pop it on my huzzh32(2ac72-esp32) board and it did absolutely nothing. thats why i moved to a board that i had a usb-debugger for since the jtag seemed to share some pins with the display on this one and i had no loose jtag.
but like i say i can use the memory on its own and the display on its own so spi seems fine
and the only change i basically make is to give the Adafruit_EPD a (-1) chip-select for sram (SRCS)
and also change from using a 3.3v to 5v

Re: EInk feather 2.13 mono
a made a little test and just create the sram class and write a text to it when it uses 3v
and it does what it should.
so this is why i wonder if my featherboard might be a dodgy revision ... seems it has had a few
it looks like https://www.adafruit.com/product/4195 that 4th picture with the coin.
