Cradio keyboards

Cradio are minimalist 34-key split-keyboards designed with no diodes, using direct micro-controller pin wiring.

Keyboard Info

• Keyboard Maintainer: David Barr
• Hardware Supported:
  • Cradio
  • Sweep
  • Hypergolic
  • Variants of the same 34-key direct pin PCB
• Hardware Availability: order PCBs using gerber files from the repository

Make example for this keyboard (after setting up your build environment):

make cradio:default

Setting Handedness

Firmware uses handedness by EEPROM as default and it must be configured once on each side. The make commands are:

make cradio:default:dfu-split-left
make cradio:default:dfu-split-right

QMK Toolbox can also be used to set EEPROM handedness. Place the controller in bootloader mode and select menu option Tools -> EEPROM -> Set Left/Right Hand

Bootloader

Enter the bootloader in 3 ways:

• Bootmagic reset: Hold down the top left key on the left half (or the top right right key on the right half) and plug in the controller on that side.
• Physical reset button: Briefly press the reset button soldered on the PCB.
• Keycode in layout: Press the key mapped to RESET if it is configured.

Swapped Pins

If you have one of the PCB variant with swapped letters Q and B / P and N, add the following code to your keymap's config.h to swap pins E6 and D7 in the firmware:

#undef DIRECT_PINS
#define DIRECT_PINS { \
    { D7, F7, F6, F5, F4 }, \
    { B1, B3, B2, B6, D3 }, \
    { D1, D0, D4, C6, E6 }, \
    { B4, B5, NO_PIN, NO_PIN, NO_PIN } \
}
#undef DIRECT_PINS_RIGHT
#define DIRECT_PINS_RIGHT { \
    { F4, F5, F6, F7, D7 }, \
    { D3, B6, B2, B3, B1 }, \
    { E6, C6, D4, D0, D1 }, \
    { B5, B4, NO_PIN, NO_PIN, NO_PIN } \
}
