NEK Type A (#5175)
* project creation and config.h import * fix name * cleanup * layout for left * working left with feather pins * full keymap * ? * let's do this * non working twimaster version * it fucking works! * bluetooth! * cleanup * use auto output for ADAFRUIT_BLE * remove auto from custom matrix * better ble auto * fix f1 * revert * fix ble * update readme * Update readme.md * Update readme.mdmaster

Natural Ergonomic Keyboard, Type A
|
||||||
|
|
||||||
|
Keyboard Maintainer: [Mike Roberts](https://github.com/ecopoesis)
|
||||||
|
Hardware Supported: Custom PCBs from https://github.com/ecopoesis/nek-type-a
|
||||||
|
Hardware Availability: https://github.com/ecopoesis/nek-type-a
|
||||||
|
|
||||||
|
## Design
|
||||||
|
|
||||||
|
This is a column-driven split keyboard using three custom PCBs connected with ribbon cables. The left and right PCBs are
|
||||||
|
passive: they only have the diodes and switches needed to make the matrix. The center PCB has an Adafruit Feather 32u4 and
|
||||||
|
MCP23017 expander.
|
||||||
|
|
||||||
|
The left matrix has its rows and columns directly connected to the Feather. The right matrix has its rows connect to the
|
||||||
|
Feather (using the same pins as the left matrix) and its columns connected to the expander. The expander uses the LUFA
|
||||||
|
hardware TWI driver.
|
||||||
|
|
||||||
|
Bluetooth is enabled.
|
||||||
|
|
||||||
|
## Building
|
||||||
|
|
||||||
|
Make and install this keyboard (after setting up your build environment):
|
||||||
|
```
|
||||||
|
make nek_type_a: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).
