Schematics

Hey guys and girls


I am playing with the RE5V1C 5V Wifi Inching/Selflock Relay Module https://www.itead.cc/sonoff-re5v1c.html). I want to use it to open and close a garage door, so I need two inputs to be able to know if thew door is fully open and fully closed.


I managed to load Tasmota onto it very easily, but I cannot get any info on the pads

ETX, ERX, TX, RX and IO2. How are they connected to the ESP8266? Does anybody have the schematic or more info?


Thank you

Marty
