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.

Item arrived right on time and was exactly as advertised. I’ve tried it out and it worked great. As always with Banggood the price is right. saved over $4 getting it from Banggood instead of Amazon. 👍
