Remove the three screws in the back of the device and pry.

Connect ESP

Remove screws and detach the main pcb from the back cover, then identify and solder wires to the TX, RX and GND in the ribbon cable solder joint to the ESP as below:

Tx - 1Kohm - GPIO 4 Rx - 1Kohm - GPIO 5

Power the ESP using an smps.
