This is a pretty basic IC for this 75% PCB that is a
collaboration between myself and @amtra5 on the /#mechkeys
Discord. I’ve already received a good deal of interest on
Reddit and have already done a Rev1 prototype run.
While this initial version utilized a Teensy2.0 for
the sake of easy and lower costs for a small run, Rev2 is
utilizing an SMD Atmega32u4.
Features list:
- 75% form factor
- MX and Alps style compatibility
- Several layout support options, picture below
- WS2812B strip support
- Support for QMK/TMK/Soarer’s firmware
- Normal and rotated Alps ISO Enter

Layout options:
The initial prototype run was a success, though at
this point it was mainly a proof of concept as we’ve changed
the controller in Rev2. Sometime soon I will be doing the
Rev2 prototype run with full SMD assembly and will most
likely have extra PCBs for sale afterwards to help make up
for some of the prototyping costs.
For the eventual GB,
I am currently in contact with several custom case makers in
the community in order to provide some simple but nice cases
for the first round GB, and perhaps a fancier case option
available for future rounds.
4-27-2017 Update:
I’ve ordered the Rev2 prototypes and they should
arrive mid next week going by previous shipping times. This
is the first test of our SMD controller design and I’ll
actually be doing the assembly myself since low quantity SMD
assembly setup costs scared me. Switching to SMD we’ve also
managed to shrink down the PCB size slightly and moved the
USB port, so I think now that it should actually fit into
any aftermarket case that a B.mini PCB could fit into,
barring the screwhole cutouts that the B.mini has on its
edge. I need B.mini dimensions though to be certain, so if
anyone could get ahold of them that would be nifty.
Bump
from hell up in this /////*. I finally
found someone to do the SMD soldering on the 2nd prototype
and I’ll have in on hand to test in a couple days. As soon
as that happens I can work with my case makers and try to
get case options available to order when the PCB GB goes
live. On a related note, I’ve contacted Matias about
possibly setting up a 75% Alps keyset to GB alongside the
PCB. Unfortunately, it doesn’t seem like Matias is very
receptive to business inquiries as it took several tries to
get my email through their spam filter. They have yet to
reply. In the meantime I’ve considered going to SP to get an
Alps 75% set going, in either DSA or DCS. While I don’t
agree with some of their business choices or some of their
past interactions with the community, working with them
would mean a cooler looking set and the chance to do an MX
companion set at the same time.
