$19.99 $19.99 Sale Save

Need even more keys than the Viterbi? Awesome, we've got a split board with up to 6 rows and 9 columns! Don't need that many rows or columns? Well that's cool too, the PCB features break off pieces to allow for 4 to 6 rows and 7 to 9 columns.

The Rev. 1.4 PCBs are able to be used with MX-compatible, Alps-compatible, and Kailh Low-Profile Choc switches.

New! The PCBs now have components pre-soldered to the board, so now, all you need to solder on are your switches and microcontrollers. Also with Rev. 1.4, the TRRS jacks have been replaced with USB-C

Item Notes

The PCB Kit includes the following:

  • 2 BFO-9000 PCBs with these components pre-soldered:
    • Push buttons for reset
    • USB-C ports (both are wired to each other, so use may use either one)
    • 1N4148 diodes

Case plates are available separately here: Plate Kit

Each half can be used on its own as well, if you want just a large macropad.

    The Name

    The name is derived from that big gun in Doom. The 'B' stands for Big, the 'O' for Ortho, and the 'F' for ... well you know.


    FR4 Plates are available for a 6x9 layout.

    For a 5x7 layout, The BFO-9000 does fit into a Viterbi case.
