46mm 20A FET LED Driver For SRK Lights.

L1: TBD FET: 70N02 D2: DIODE_MBRS540. Connects between D1 and C+ pad. Diode D1 SOD-323. C1 is 10 uF. Resistors are 19.1K and 4.7K, 1% Regulator chips are AMC7135 Processor is ATTINY13 or similar LED connects to the + and – holes. C- & C+: are for user selected large capacitor. SW+ & SW-: at for momentary switch contacts.

The driver mode configuration “stars” are marked 2 to 4 on the MCU side of the driver.

Battery plus is the large center pad on the reverse side of the board.
