I came across this recently while browsing Amazon. It looks like quite a neat board and that looks like an ESP32 or ESP8266 in the diagram. With a USB-C power in, screw connectors for signal and power outputs, 5V/3.3V conversion and with some other pins available as through-hole or pad connectors, it seemed like a nice little board.
I wonder if anyone has experience with this one and knows it it can be re-flashed conveniently?
But some developers might making These unflashable.
I also don’t see any USB TTL converter in the product which could mean it need a USB To TTL External converter
