    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).

    Ordered two: - One was missing some of the header pins; - Other has the relay standing proud of the board - barely any solder on the load current pins. Solved both problems without too much trouble, but beware of QA issues. Flashed Tasmota firmware onto them, using template LC-ESP12-1R-MV and working fine.

    Great device for the price! Had it flashed with Tasmota using Tasmotizer and toggling the onboard relay under 10 minitues!

    Very good product. Pin header can be used to do lot of things like handle many other relays.

    La fuente incorporada es suficiente para el modulo, pero pequeña en caso de necesitar adjuntar circuitos externos a las salidas libres.

    Works great. The only remark is that the usb port is for power only, programming goes over the serial interface with an external ftdi adapter.
