This has been a project of mine for a while now and I
finally think I reached a spot where these could go into
production.
So, what’s this about?
People who own OTD keyboards know that the PCBs can
be a royal pain in the butt. They are PS/2 only and a good
amount of them aren’t reprogrammable. Maybe they’ve been
desoldered and patched up by the previous owners, maybe even
completely destroyed. Seeing some of the original PCBs
trading for rather high 3 figures, it’s time to put an end
to this.
This IC is about a new PCB that matches the
original one as closely as possible while still offering
most of the advancements we had in PCBs since then.
The
person who graciously lent me an OTD to take measurements
from was interested in making an Alps build, so I had to
take plate measurements as well and ended up making all
kinds of different plate configurations, some of these are
likely to be offered too.
PCB specs:
- USB but you’ll have to hardwire a cable, just like the original PCBs did with the PS/2 cable
- Fits: OTD 356.2, 360c, 456gt, The Cheat, (356n and 356n mkii, but only with a different plate because it does not support the original layout), and is very likely to fit 356cl, 356cl DGE and 356cls, so every TKL except the 356l
- Layout: Normal WKL TKL layout with and without blockers
- Material: 1.2mm thick CEM-3 with red Soldermask, just like most of the original PCBs
- LED indicators for Caps Lock and Scroll Lock
- Supports MX and ALPS switches, with all possible caps lock positions with ALPS switches
- Powered my an Atmega32u4, so programmable via QMK and TMK (even Keyplus if you want)
- Fully assembled, no in-switch diode soldering like on the original PCBs
-
Plates:*
In case some people have a working original PCB but still want to upgrade to this one I’ll be likely offering plates too. These are as close to the original as possible and have all of the little slits and cuts and everything.
Many different materials and layouts (two versions of ALPS fullplate, MX fullplate, MX halfplate, etc.) are technically possible but not all of them would make it, so if you are interested in plates fill out the form accordingly. The plate is based on the 456gt plate and fits the 456gt, 360c and 356.2. It does not fit the Cheat, the 356cl and the 356cl DGE. Fitment on 356n and 356n mkii is not confirmed but possible. -
Misc. parts:*
If there’s enough demand sourcing a nice thick coiled USB cables that go well with the PCB could be a possibility.
Another possible addon could be precut bandaids because the PCBs are 1.2mm thick and as such benefit a lot from band aids.

If anyone gets the chance to crosspost this into foreign forums, mainly chinese and korean ones, I’d be grateful because I don’t speak those languages and don’t trust google translate enough for that.
Pics(Sorry for the bad pics, I forgot to take good ones when I still had the PCB here, I’ll make some new renders later):
These pics are from an old version without the support for winkeys, everything else is the same
