NOTE: I made this board to suit my needs, and decided to share the board in case someone needed. If you want something more customized for your needs, component types (eg. SMD or through hole), the microcontroller you want to use, the shape and size of the board, leave a comment I will make something just for you.

This project was made to control Light engines for fiber optics star ceiling, I made this board to be used with ESPHome or WLED so you can add them to homeassistant. There are option to further expand and add more RGB or WS2812 LED strips, my choice of connectors and the traces on the board are quite wide so you can connect up to 12A per RGBW channel without any problems.

If you have a the twinkle option in your Light Engine, you can add any Step/Dir stepper driver commonly found in 3ds printers, there are videos to convert unipolar (5 wires) stepper motors into bipolar (4 wires) on youtube.

If you want sound reactive option you can add a INMP441 microphone.

Where to find the parts you need (I don't have any affiliate fell free to buy where is more convenient for you)

• VH 3.96 Connectors
• JST Connector (You need to cut the female connectors to size I can't find 22pin connectors)
• MX2.54 Dupont Connector (3 pin)
• XH 2.54mm Connector (4 pin)
• ESP32-S3-DevKitC
• INMP441 MEMS Mic
• Stepper Driver A4988
• FDD8447L MOSFET
• SMD Resistor (Use 0805)

IO42 is to control Computer PSU, you can just leave it. IO1/IO2, RX/TX are for extra things you may want to connect, you can leave them.
