Nice development board. Can be flashed with a TTL flash device on the GND-TX-RX-5V connections. I flashed 2 devices with Tasmota firmware. GPIO5 should be assigned to Relay1 in Tasmota to control the on-board relay. GPIO16 of Tasmota controls the on-board programmable LED, this is inverted (eg use Relay2(i) to activate the programmable LED). You can also get more information on : http://www.chinalctech.com/cpzx/2/472.html (this link shows how to program the board with a Arduino sketch).
