    PCB Review Request: RGB LED String Controller via NodeMCU ESP8266 Wifi Module

    Hello all, I've recently completed the design of a circuit schematic and PCB for controlling an RGB LED string using a NodeMCU ESP8266 WiFi module. The circuit operates on a 12V DC input and utilizes three relays to control the red, blue, and green LEDs respectively. The LED string itself draws...
