Serial Connection
Please see the Hardware Preparation page for general instructions.
Step 1.
Be sure it is NOT plugged in! Remove the 4 triangle screws. Triangular 2.3mm Screwdriver required!
Step 2.
Solder cables to the ESP Pins
Step 3.
Connect serial adapter and make a shortwire between Pin IO0 and GND during startup. (For entering flashmode) RX and TX must be crossed.
Step 4.
Flash Tasmota

Known Issue
There is a newer hardware revision (v2.3) which is currently not supported out of the box. It is flashable but not working correctly. Should be fixed: See #4297 and latest development release. UPDATE: Configuring the module as Teckin instead of BlitzWolf SHP2 works for this hardware revision. => this document needs to be updated with the alternative board + wiring (from issue #4303) .
