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.
