# handwired/erikpeyronson/erkbd
|
||||
|
||||
|
||||
|
||||
3D printed, handwired 44 key split keyboard featuring two encoders, two 1.3" 128x64 oled displays using the waveshare rp2040zero development board.
|
||||
|
||||
* Keyboard Maintainer: [Erik Peyronson](https://github.com/erikpeyronson)
|
||||
* Hardware Supported: See keyboard repository on [github](https://github.com/erikpeyronson/erkbd)
|
||||
* Hardware Availability: See keyboard repository on [github](https://github.com/erikpeyronson/erkbd)
|
||||
|
||||
Make example for this keyboard (after setting up your build environment):
|
||||
|
||||
make handwired/erikpeyronson/erkbd:default
|
||||
|
||||
Flashing example for this keyboard:
|
||||
|
||||
Enter bootloader, drag and drop .uft2 file on the removable storage
|
||||
|
||||
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).
|
||||
|
||||
## Bootloader
|
||||
Enter the bootloader in 3 ways:
|
||||
|
||||
* **Bootmagic reset**: For left half hold down the key at (0,0) in the matrix (correspons with the tab key) and plug in the keyboard.
|
||||
For left half half the key is (4,5) (corresponds with the backspace key)
|
||||
* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
|
||||
* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
|
||||
Enter the bootloader in 3 ways:
