BLF switch board DDm-K2-SW [rev01][tried and tested]

2 layer board of 0.61 x 0.57 inches (15.4 x 14.4 mm)

Total Price: $1.70

Daughter board for the DDm-K2 driver board.

<https://oshpark.com/shared_projects/F9jb3vFP>

The switch is a NO SMD 6.2x6.2x3.1 mm tactile type. The LEDs have 0805 footprints. Normally R1 is not populated. A jumper or small-value resistor here wires the two LEDs to be driven in parallel.
