WLED controller board for D1 mini (Wemos)

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

• preflashed with WLED
• 5V/GND connector for input voltage
• 5V/GND connector for LED strip
• up to 3 data lines with ESP8266
• up to 4 data lines with ESP32
• support for LED strips with clock signal
• level shifter for LED signals (3.3V -> 5V )
• connector for microphone sensor or button input (3.3V, GND, A0)
• resistor for data lines if necessary
• capacitor to stabilize input voltage
