Originally runs eWeLink software so it has to be flashed over serial. Plastic case is disassembled without any screws. The wi-fi module has a SMA-C01 sticker on it and the module PCB is marked SM-001 v1.0 2018-11-14.
A lot of GPIOs are broken out at the bottom of the module but only some are soldered to the main PCB. TX and RX have no solder applied!
