This design was apparently orphaned quite early. I haven't found a schematic (yet). It has esp32 module, 6 mechanical pushbuttons (in addition to reset & boot), linein & headphone jack (amplified? apparently not), speaker connectors, battery charge circuit & separate power & console connectors. sdCard interface will have to be deduced by trial & error. DIP switch legend offers some clues. Competently, if cheaply, made.
