# Kyria
|
|
|
|
|
|
|
|
An ergonomical 40% split keyboard
|
|
|
|
Keyboard Maintainer: [splitkb.com](https://github.com/splitkb)
|
|
Hardware Supported: Pro Micro 5V/16MHz and compatible.
|
|
Hardware Availability: [splitkb.com](https://splitkb.com) and partners.
|
|
|
|
Make example for this keyboard (after setting up your build environment):
|
|
|
|
make splitkb/kyria/rev2:default
|
|
make splitkb/kyria/rev2/proton_c:default
|
|
|
|
Example of flashing this keyboard:
|
|
|
|
make splitkb/kyria/rev2:default:flash
|
|
|
|
Replace "rev2" with "rev1" if you have a Kyria of revision 1.4 or below.
|
|
Not sure what revision yours is? It is printed on the outer lower edge of the PCB!
|
|
As a rule of thumb, all Kyrias sold after January 1st 2022 are revision 2.x.

## Proton C Conversion Guide
|
|
|
|
If you're one of the lucky people to have Proton Cs to use with their Kyria, there are a couple of caveats to getting this working.
|
|
|
|
1. You need to have 2x Proton Cs, as you cannot mix and match with Pro Micros or Elite C's. They both need to be Proton Cs.
|
|
2. You'll need to do some modding to enable proper support with the Proton C.
|
|
|
|
By design, the Kyria uses every available pin on the Pro Micro footprint. This includes using D3 (RX) for RGB. This poses a challenge with using the Proton C, since it needs both the TX and RX pins. The Proton C needs both pins, especially if you plan on using Full Duplex Serial.
|
|
|
|
To fix this, you need to break off the last header position on the right-hand side on the footprint. This is the `TX0/D3` pad. Leave this pad without a header connected to.
|
|
|
|
From the A9 pin on the Proton C, you want to run a wire from it to the `SDA + Extra Data` pad near the TRRS jack on the PCB. This will allow for proper, full duplex communication over the TRRS cable.
|
|
|
|
To get RGB working properly, as well, you want to run a wire from the `A3` pin on the Proton C, next to the GND and DFU pin, right under the USB port. Run this to the `TX0/D3` pad (the one you left without a header pin on the PCB).
|
|
|
|
Once you've done that, you can solder in the Proton C. and flash it.
