Thanks. I believe that's more or less the board I soldered together by hand. Or, perhaps a somewhat simpler version. Back then I don't think FluidCNC existed, it was just a grbl build for esp32. Edit: It was this board https://www.tindie.com/products/33366583/grbl_esp32-cnc-development-board-v41/ https://www.tindie.com/products/33366583/grbl_esp32-cnc-deve... I soldered manually. Same developer though.
