RGB Matrix Panel Drive Interface Board for ESP32 DMA

I’m fan over years of electrodragon’s products but this one I don’t have words to describe this crappy one, . – First, lot of hand soldering connector and they should have been made by a rookie, not nice, even not sure they will do the job (if I get this to work) – We don’t know which side to plug ESP32, should have been complicated to put a picture with the device plugged in so we can know how to plug? – So trying to match with silkscreen pin name to plug ESP Pico Dev kit? no way, no silk on PCB, don’t try also to read 5V or GND on big connector there is no silk either – So my guess, check the powering and placing on documentation? no way either, no documentation except for software configuration. Going immediately to case “things to get out one day when it will have basic documentation”
