LFK 78 Question

Does the LFK 78 support cherry too or just alps?




Solder version supports both. Hotswap is MX only.


Just read that the 68-keys variant of the LFK 78 is compatible with the VA68M case.

Anyone knows for which generation of the VA68M or if it also fits into a Ducky × Varmilo Miya Pro case? IIRC more recent VA68M use USB-C connectors like the Miya Pro does…

Not sure. Best bet is to Email Scott on the website. He used to respond.

Anyone know another way to get in touch with him? Emailed last week about something. He never responded.

The LFKs def won’t fit any USB-C cases- the tolerance on the hole is tight and the USB-C hole in the new cases isn’t tall enough for the USB-A. You could definitely bore it out a bit since it’s plastic.

At 11:39 here you can see the pcb and plate of the USB-C version- looks like they’re using an identical case (just plastic obv) and plate, and port positioning on PCB looks the same. I have the older Aluminum VA68M version, with both the hotswap and solderable LFK PCBs, and I have a loose VA68M USB-A pcb so I could take measurements if you like.
I’m sure you could compare old mechmarket listings for pics too. https://youtu.be/3QQGzY2XoBk

Bumping my last question.
Still haven’t heard back from him. Anyone know his username on any of the regular forums?

u/LFKeyboards on Reddit.

FWIW I haven’t gotten a response from LFKeyboards for a while now, even when writing on Reddit, contact form or responding to order emails. My guess is that they are busy and have a backlog of things.

@llisandro I’d be interested in those measurements, if you’re still offering those, I’m kind of in the same boat as @XTaran and would love to add a 68-key variant of LFK78 to a white Miya Pro case.

LFKeyboards is a one man operation from what I gather. Orders take a long time. Especially if you order a hot swap board, I believe he solders the hot swap switches on himself. I ordered a hot swap board and it took three months to ship. He is not very communicative.

He is not a scammer, but be prepared to wait!

Sure, it’ll take me a bit, but I have 2 LFK PCBs, plate and a loose VA68M pcb to compare. Unfortunately I don’t have any calipers, but I can use a ruler and take some pics. Like I said, I think the plates look identical in the Miya.

One of my LFK pcbs I actually bought broken on mechmarket, and a pad from the USB port has been jumped. I’ve never gotten around to trying to fix it, I wonder if you could swap the piece with a type C…

ok, here’s a pic. This is an older LFK78 PCB.Version not known, but it’s an early one. The Varmilo PCB is from a “VA68MN” model that I believe was sold by Drop in ~2017, based on its age and LED config (I bought it second-hand). Here’s another build gallery with more pics (not mine). The Miya Pro case looks damn-near identical. Is it possible to use the same exact case design since the VA68M is die-cast?
Again, no calipers, but I measure the varmilo PCB to be 31.8 x 9cm, and the LFK is about 1-1.5 mm wider. PCB edge to center of microUSB port on VA68M is 4.50 cm, ~4.65 cm for the LFK. The LFK PCB and plate do fit in my Varmilo Aluminum case.
I don’t think the Miya Pro ever came in a edit:mini USB option. Given that there’s a little indent around the USB port on the Miya Pro, I’d think you could Dremel out the hole to accommodate the mini port. I got all my LFK PCRs second-hand on mechmarket after waiting for things to coming in stock on LFKeyboards.

@llisandro Thank you very much, that helps a lot!
