Serial Flashing

The only way to flash the module is by soldering 4 wires to the RX/TX/3V3/GND pins on the ESP-07. The PCB has no serial pinout connectors. For connecting the ground (GND) on a V5.0 Modul you can use one of the 2 GND pinout connectors from the PCB. For flashing the moduls enable the flashmode of the ESP, connect PIN4 (GPIO00) to GND.

!!! Don’t flash the module when it is connected to mains power. Use only a 3.3V USB Adapter for flashing!!!

GPIO00 - Module Pin 4
GPIO02 - Module Pin 3
GPIO04 - Module Pin 2
GPIO05 - Module Pin 1
GPIO12 - Relay1 ( High = Off)
GPIO13 - Relay1 ( High = On)
GPIO14 - Relay2 ( High = Off)
GPIO16 - Relay2 ( High = On)


For use the V5.0 Modul with the “EXS Relay(s)” profile you must change the “Module parameters” (see picture below)

Now you see in device setup

The output pins of the V5.0 are reversed on the PCB. You must use “out1” for Relay2 and “out2” for Relay1 !!! This is the only way for support both Moduls with Tasmota. (thanks for this Note to Theo Arends)
