Description
- Constant current LED driver with 8 channels based on PT4115.
- Controlled by ESP32, for use with ArtNet protocol.
- Power supply from 8V to 30V (use suitable capacitor voltage) allow connecting several LEDs in series on each channel.
- Change 0.13R resistor to set max current (Current = 0.1/R).
- Some pin headers for future extensions, like servo to make a tiny moving head projector.
Provided source code is for ArtNet control with 2 RGB and 2 White with following DMX config :
- Master dimmer
- RGB0 Color
