# 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_d 6 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_a 0 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_a 1 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_a 2 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_a 3 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 15 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 14 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 16 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 10 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 1 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 2 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 3 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 4 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 5 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 7 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 8 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
, <&pro_micro_d 9 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
;
};
