Introduction

I ordered a RGB+CCT controller online and to my surprise the device came with a new Tuya WiFi module instead of an ESP module.

Now I am trying to swap the WR3 Tuya WiFi module with an ESP-12f module.


In the following steps I will display my findings.

Matériaux

Outils

Étape 1 - The PCB on which the Tuya WR3 module is soldered on.

I desoldered the WR3 module to check the connections with my meter and also used a lamp to expose the traces.


I checked the conenctions and it seems that only RX, TX , VCC, GND and EN are connected.


I found this thread, but still do not know how to connect it properly.

I will figure out the software side.

The ESP is used with Tasmota installed and communicates with the IC over serial.




Étape 2 - The Top and bottom side of the whole PCB.

This shows the top and bottom side
