# TrueStrike42
![truestrike42](https://github.com/byungyoonc/TrueStrike42/blob/main/doc/res/truestrike42-built.jpg?raw=true)
TrueStrike42 is a columnar staggered unibody split Hall effect keyboard designed to maximize performance and minimize finger fatigue.
Hall effect part of this firmware code is a derivative work of Cipulot's code.
OLED display part of this firmware code is a derivative work of Dasky's code.
* Keyboard Maintainer: [byungyoonc](https://github.com/byungyoonc)
* Hardware Supported: RP2040 development boards with Pro Micro pin layout
* Hardware Availability: https://github.com/byungyoonc/TrueStrike42
Make example for this keyboard (after setting up your build environment):
make truestrike42:default
Flashing example for this keyboard:
make truestrike42:default:flash
OR
Copy the built `uf2` firmware file into `RPI-RP2` drive when the controller is in the bootloader mode
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 2 ways:
* **Physical reset button**: Quickly double-press the button on the back of the PCB
* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
