## Compile

go to qmk top directory.
```
$ cd qmk_firmware
```

build
```
$ make sol:default

```
## Compile

go to qmk top directory.
```
$ cd qmk_firmware
```

build
```
$ make sol:default
```

After the initial flash with AVRdudess, you should be able to flash using this:
```
$ make sol:default:dfu
```

# Sol

![Sol](https://cdn.shopify.com/s/files/1/0008/8827/5005/products/CqdJAno_2048x2048.jpg?v=1533825028)

Sol is a split ergonomic keyboard with ortholinear alphas and several modifier layouts. It can use up to 88 RGB LEDs, with per-key backlighting and underglow. The boards have presoldered components, including type C ports and ATmega32U4. Sol, when used with dual power supplies, is the brightest keyboard on earth.

Keyboard Maintainer: [Legonut](https://github.com/Legonut)  
Hardware Supported: Sol PCB R1.0, R1.1  
Hardware Availability: [RGBKB](https://www.rgbkb.net)

Make example for this keyboard (after setting up your build environment):

    make sol:default

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).
