This board is designed to connect addressable LEDs/Neopixel strips and handle them with the WLED firmware. Other firmware can be used as well.
- ESP32-WROOM-32E
- 5,5mm / 2,1mm barrel jack connector for input voltage
- 2 output lines for LED data and LED clock or relais
- level shifter for both outputs (3.3V -> 5V )
- resistor for data line
- support for LED strips with clock signal
- connector to flash firmware with CP2104 (3.3V, TX, RX, GND, IO0, GND)
- ❗ Maximum 5A ❗
- connector for digital input (3.3V, GND, IO4) (IR remote control for example)
- connector for addon shields (GND, IO32, IO15, IO14, 3.3V, GND, SENSOR_VP)
- 1 x WLED All-in-one ESP32 Controller presoldered from https://jlcpcb.com/
