# TIDBIT
![TIDBIT](https://nullbits.co/static/img/tidbit1.jpg)
A very moddable 19-key numpad kit built by nullbits. [More info at nullbits.co](https://nullbits.co/tidbit/)
* Keyboard Maintainer: [Jay Greco](https://github.com/jaygreco)
* Hardware Supported: TIDBIT Rev1, Pro Micro comaptible MCUs.
* Hardware Availability: [nullbits.co](https://nullbits.co/)
Note: If you are seeing issues with MacOS and keyboard hangs after sleep, make sure `NO_USB_STARTUP_CHECK = yes` is set in your rules.mk.
Adds experimental "Remote Keyboard" functionality, which forwards keystrokes from an external macropad, keyboard, or numpad over UART/TRRS, removing the need for an additional USB connection.
## Bootloader
Enter the bootloader in 2 ways:
* **Physical reset button**: Briefly press the button on the back of the PCB
* **Keycode in layout**: Press the key mapped to `RESET` if it is available
Make example for this keyboard (after setting up your build environment):
make nullbitsco/tidbit: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).
