Revision 5 features a speaker and is matte black! It supports both Cherry MX and Matias/ALPS switch footprints for both the 2u space and grid layouts. All components (USB Mini port, diodes, Atmega32u4, 470 ohm resistors for keyswitch LEDs, speaker, etc) are pre-soldered and it's ready for keyswitches and LEDs.

The PCB features a reset button for quick programming (milled bottoms have a hole at the precise location of this). The standard keymap is already flashed to unit.

There are 5 mounting slots that are compatible with the milled bottom. Other mounting holes (2.85mm in Rev 5) are for plateless mounting on cases. Then remaining pins on microcontroller are pinned-out for easy modding.

Revision 5 contains the new QMK bootloader - to see all firmware notes, check out the release:
