MacroBoard is a 9-key hot-swappable mechanical macropad powered by Seeed XIAO RP2040. The keyboard has 9 Kailh hot-swappable sockets compatible with any 3-pin or 5-pin MX switch, giving you the ability to choose the switches that suit you best. The keyboard also includes a rotary encoder with a push button and each key is backlit with an RGB LED.
- Uses Seeed XIAO RP2040, a small form factor board based on the Raspberry Pi RP2040 microcontroller.
- Supports MicroPython and CircuitPython.
- Kailh hot-swappable sockets compatible with 3-pin and 5-pin MX switches.
- Rotary quadrature encoder with push button.
- SK6812 reverse-mounted addressable RGB LEDs to backlight each key.
- Power and communication through a USB-C type port.
- Compatible with KMK keyboard firmware.
- Compatible with Windows, macOS, and Linux operating systems.
- Dimensions: 61mm x 81mm x 31mm (without case), 66mm x 86mm x 35mm (with 3D-printed case).
To set up the keyboard to work with CircuitPython and KMK Firmware, follow these steps:
- Enter Bootloader Mode
- Press and hold the "BOOT" button.
- Connect the Seeed XIAO RP2040 to your computer while still holding the button.
- Your computer should now show a new drive, RPI-RP2.
- Download the firmware for Seeed Studio XIAO RP2040.
- Drag the .uf2 file to the drive RPI-RP2.
- Check the drive. The name should now have changed to CIRCUITPY.
- Download the file neopixel.py and copy it to the root directory on drive CIRCUITPY.
- Download the KMK Firmware repository as a ZIP file.
- Extract all files from de ZIP file and copy the kmk folder to the root directory on drive CIRCUITPY.
- Download the files code.py and boot.py from the firmware folder.
- Copy the files to the drive CIRCUITPY.
- Restart the keyboard by pressing the "RESET" button or disconnecting and reconnecting to the computer.
The key mapping defines the function and behavior of each key using a keycode or set of keycodes. The following code, which can be found in the file code.py, shows the key mapping for MacroBoard.
# Keymap
keyboard.keymap = [
[KC.LCTRL(KC.LSHIFT(KC.TAB)), KC.LCTRL(KC.M), KC.LCTRL(KC.TAB),
KC.MEDIA_PREV_TRACK, KC.MEDIA_PLAY_PAUSE, KC.MEDIA_NEXT_TRACK,
KC.LCTRL(KC.C), KC.LCTRL(KC.V), KC.LGUI(KC.SPACE),
]
]In this example, the keys in the first row can switch between browser tabs and mute a tab. The keys in the second row can control the media player, and the keys in the third row function as Ctrl+C, Ctrl+V, and GUI+SPACE.
| COLUMN 1 | COLUMN 2 | COLUMN 3 | |
|---|---|---|---|
| ROW 1 | CTRL+SHIFT+TAB | CTRL+M | CTRL+TAB |
| ROW 2 | PREV TRACK | PLAY/PAUSE | NEXT TRACK |
| ROW 3 | CTRL+C | CTRL+V | GUI+SPACE |
You can find a list of all available keycodes at the KMK Firmware's wiki.
The CircuitPython firmware, KMK Firmware, and NeoPixel library are managed and maintained by their respective developers.
