Overview

Set of two 3 Channel LM317 Constant Current LED driver PCBs (parts are not included.)

Details

The board can work with common anode or common cathode LEDs. 4 x 16ohm 0.25W resistors per channel can be used to get 312mA current (standard for 3x3 chip LEDs.) LM317s do get hot, so the best input voltage is Vf + 2V. Heat sinks are recommended (required if Vin is higher than Vf + 2V.) CAUTION: LM317's tabs must be isolated if all are mounted to the same heat sink.
