This features a speaker! It supports both Cherry MX and Matias/ALPS switch footprints for both the MIT 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 is white.
The PCB features a reset button for quick programming (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 holes on the top and bottom plate. Other mounting holes (2.85mm in Rev 2) are for plateless mounting on cases. Then remaining pins on microcontroller are pinned-out for easy modding.
Revision 2 comes with the new QMK bootloader - for details on this and the rest of the firmware, check out the release notes: https://github.com/qmk/qmk_firmware/releases/tag/preonic-2.0
