100W RGB LED Constant Current Driver

A constant current driver made to to drive 100W RGB COB LEDs

Interactive BOM

Features:

• 3 Constant current outputs for Red, Green, and Blue channel
• Controlled with an ESP8266 running WLED and connected over Wi-Fi
• Panelized in a 2x2 panel of 100x100mm for minimal fabrication costs at JLCPCB
• BOM cost is kept low at around $6 per board

Pinout

Bring-up and Usage

• Follow the iBOM and solder all items onto the board.
• Attach the programming device onto the mezzamine connector on the top left of the board
• Program the ESP8266 with WLED
• Setup WLED with a single analog RGB channel attached to it. The pinouts should be:
  • Green: GPIO 13
  • Red: GPIO 12
  • Blue: GPIO 14
• Unplug the programming header and attach the LED and a 24V/5A power supply to the screw terminals
• Connect to the ESP's Wi-Fi network and turn on the lights!
