5+1 7135 driver for Solarstorm/Fandyfire K2 lights.
Revision changes
- New
Needs the DDm-K2-SW daughter board for the tactile switch and indicator LEDs:

‘Standard’ BLF parts list, except for:
- R1 and R2 are populated if MCU pin 7 is used for cell voltage monitoring. This could, however, be done using the software-only method of Vcc vs. the internal 1.1 V reference.
- R7 is populated when re-purposing pin 7 to drive a second indicator LED, as per the stock driver.
- There is an R1 on the back of the switch board. A jumper here rewires the two indicator LEDs in parallel, both to be driven from MCU pin 3.
- C3 = 10 uF is optional
- C4 = 100 nF is optional
