Hardware Supported: Pro Micro
Make example for this keyboard (after setting up your build environment):
make handwired/splittest:default
Example of flashing this keyboard:
make handwired/splittest:default:avrdude
See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
Wiring
------
- Add switches to both Pro Micros across B3 and B6 pins
- Add pull-up resistor to left side between VCC and F6
- Add pull-down resistors to right side between GND and F6
- Connect the following pins on both sides together: D0, D1, GND, VCC
- Add I2C 4.7kOhm resistors between D0 and VCC, and D1 and VCC
- Wire Di of RGB strip for each half to D2
