**Reset Key:** To put the Eagle/Viper V2 into reset, hold caps lock key (`K2A`) while plugging in.
See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
## Hardware Notes
The Duck Eagle/Viper V2 PCB consists of:
### Microchips
2 74HC237D 3-to-8 line decoders
1 Atmega32u4 microcontroller
2 WS2811 LED controller
## Notes
Thanks to Ralf Schmitt for previous implementations in his [TMK fork](https://github.com/xauser/tmk_keyboard/tree/xauser/) and few helping words.
Based heavily on Rasmus Schults [Duck Lightsaver QMK Port](https://github.com/qmk/qmk_firmware/tree/master/keyboards/lightsaver)
Special thanks to profanum429 for debugging help and contributions to support the Viper and LED indicators.
