Esp8266. nice strong well designed board. There is no documentation so you have to do some reverse engineering- need to solder some headers and jumpers.

Great product, first relay flicker on boot (default setup) but it can be fixed by connecting first relay to some other (GP)IO (I connected it to IO15). Instead of jumper, for first relay make wire and connect it to IO4/5/15.. Flashed with Tasmota and it works great.

Please be aware that you have to solder at least the four jumper terminals, that come with the board, for the relays to work. I did not know that beforehand. However I successfully flashed TASMOTA firmware to the board to use it in my smarthome environment.

Showed up with a Capacitor torn off, Solder all over the board, Headers fell off in shipping, Ill have to replace the caps, Led & SMD diode & hope it works.. I guess for 13USD this is what to expect right ?
