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 (a Torx T6 works well too)! Triangle screws

Step 2.

Solder cables to the ESP Pins ESP Pins soldered cables

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. shortwire during startup

Step 4.

Flash Tasmota
