WLED All-in-one ESP32 Controller

This board is designed to connect addressable LEDs/Neopixel strips and handle them with the WLED firmware. Other firmware can be used as well.

Features

• 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)

BOM

• 1 x WLED All-in-one ESP32 Controller presoldered from https://jlcpcb.com/
