I’ve had prototypes made for a replacement PCB for
the Leopold FC980M. The goals for this were to 1. allow more
layouts and 2. allow full programming (QMK). My proto only
has 1.5-1.5-7-1.5-1.5 bottom row, but others can be added. I
did this because this started out as a personal project so I
could use my OEM Dolch PAC caps with the board.
On the
electronics side, it’s a direct drop-in. The OEM FC980M has
three PCBs: 1. main (switches, controller, etc) 2. middleman
(DIP switches, pass through from USB port to main PCB) and
3. the USB port. This PCB bypasses the middleman and plugs
directly into the OEM USB port PCB, allowing super easy
installation. The difficult part of this is having to modify
the plate to accommodate other layouts - I had to cut some
switch spots into it with my Dremel tool. It was pretty
straightforward but I know some people don’t like the idea
of that. I’d be interested in looking into getting some
replacement plates made if there’s interest.
Things I
could probably add for a “production version”:
-More
layouts
-In switch LED (nice feature since Leopold
doesn’t offer this on their stuff)
-SIP sockets for the
indicator LEDs
-ISO Support? idk
-A cooler color
than green (it’s cheap so I used it for protos idc)
-A
smaller JST connector on the main PCB (probably SH or
something, I’ll look into them some more bc I forget what
the codes/sizes are)

In the above picture my jumper cable is soldered to
the USB board - I didn’t feel like waiting for those JST
connectors in the mail
Here’s an idea of the modding I had to do the plate,
I didn’t feel like spraying it so don’t tell me I should
have, I know but idc enough (prototype). The stabs didn’t
need any work, except for the spacebar one (had to cut areas
for them since the plate initially blocked em) so it’s all
just easy straight cuts to make room for the switches
I’m just trying to gauge interest, there’s no
concrete plans to run this as a fully-fledged GB as of yet.
