The Arduino LED driver is an Arduino-compatible project designed to control many LED strings in applications such as Christmas and party lightning.
Specifications:
- 4 high-power LED strings using AL8808
- 18 regular LED strings using BCR420UW6
- 12VDC input voltage (standard 2.1mm barrel jack)
- Arduino-compatible ATmega328P, programmable by ISP (no USB)

Note that there is a small design error in the current revision of the PCB. The DFLS204L diode footprints are backwards. However, it is perfectly possible to solder the DFLS204L diodes in the proper orientation.
