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 breakoff pieces to allow for 4 to 6 rows and 7 to 9 columns.
The Rev. 1.1 PCBs are able to be used with MX-compatible, Alps-compatible, and Kailh Low-Profile Choc switches. The cheaper Rev. 1.0 PCBs do not have Kailh Low-Profile Choc support. There are no functional improvements between the 1.0 and 1.1 revisions.
The PCB Kit includes the following:
2 BFE-9000 PCBs
2 Push buttons for reset
2 TRRS jacks
108 1N4148 diodes (if you want fewer diodes, please request this in your order notes so we don't waste diodes)
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.
Here's the case files for a sandwich-style case are still under development, but one can be generated easily via a combination of KLE and SwillKB Builder.
Pre-ordering for acrylic cases will be available in the future, but for now, just the PCB Kit will be available. Please fill out this interest check form so we can figure out which sizes and colors to produce: BFO-9000 Acrylic Case IC
The build guide is identical to that of the Nyquist except for the additional rows and columns, so you can use this guide.
