# KinT Blackpill Edition
This is a fork of Michael Stapelberg's [KinT project ](https://github.com/kinx-project/kint ) with the following modifications:
* Replaced Teensy with STM32F411 Blackpill controller (`blackpill` directory)
* Reduced PCB size to 100 x 86 mm
* Use Vial firmware. Source code is in my [fork of Vial ](https://github.com/dcpedit/vial-qmk-dev/tree/vial/keyboards/dcpedit/kint_bp )

## Parts for Build
| Component | Qty | Notes |
| --------- | --- | ----- |
| SMD LEDs | 4 | Can be any color [Link ](https://octopart.com/apt3216qbc%2Fd-kingbright-5355642?r=sp )
| SMD 10k resistors | 4 | [Link ](https://octopart.com/crcw120610k0fkeac-vishay-20811529 )
| Molex 13 pin connectors| 4-6 | Needed if you don't want to desolder old ones [Link ](https://octopart.com/39-53-2135-molex-7670149?r=sp )
| STM32F411 Blackpill | 1 | AliExpress [Link ](https://www.aliexpress.us/item/3256801269871873.html )
| Panel mount USB-C | 1 | Amazon [Link ](https://a.co/d/cRoqHqx )
| Socketed headers | | Only needed if you want to socket your Blackpill.
## Bluetooth + ZMK build
You can now use the Pillbug dev board along with ZMK firware to make this a wireless mod. Basically, just swap out the Blackpill with a Pillbug and add a battery.
| Component | Qty | Notes |
| --------- | --- | ----- |
| Pillbug | 1 | MechWild [Link ](https://mechwild.com/product/pillbug/ )
| 2000 mAh battery | 1 | Amazon [Link ](https://a.co/d/hlTVT1p )
v2022-08-05 of the PCB requires you to bridge the 3.3v pins with a wire. You can do this easily after soldering the controller in place and tacking a short wire with stripped ends to the existing solder joints on the same side as the LEDs/resistors. The diagram below shows you which pins.

The current version in the repo does not require this.
If you're using a battery that's larger than 500 mAh, short JP1 on the back of the Pillbug to enable "Charge Boost" (changes charge rate from 100mA to 500mA)
