# Cradio
|
|
|
|
Cradio is a firmware for a few 34 key keyboards, including Cradio, Hypergolic and Sweep.
|
|
|
|
## Pin arrangement
|
|
|
|
Some revisions of the aforementioned PCBs have slightly different pin arrangements compared to what's defined in [`cradio.dtsi`](./cradio.dtsi). If you need to swap a few keys for your particular PCB, you can easily reorder the `input-gpio` definition in your own keymap file (i.e. in `zmk-config/config/cradio.keymap`):
|
|
|
|
```dts
|
|
/* Adjusted Cradio pin arrangement */
|
|
/* The position of Q and B keys have been swapped */
|
|
&kscan0 {
|
|
input-gpios
|
|
= <&pro_micro 6 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
|
|
, <&pro_micro 18 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
