LDO version of the Yezl Y3 driver, for 2S lights.
- Suggested LDO: MIC5235-5.0, SOT23-5
- C1, C2, C3: 4.7 uF (but 2.2 - 10 uF is OK), X5R/X7R
- R5: 10 ohm

DDm driver for Solarstorm/Fandyfire K2 lights.
Revision changes
- Full size SOT-89 pads for the 7135
- Unmasked L+ vias, to be solder-filled
Needs the DDm-K2-SW daughter board for the tactile switch and indicator LEDs:

‘Standard’ DDm 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.
