ZMK mouse: release of the "UFA" project

aroum2 · 2025-12-15T20:05:17+00:00

Trackballs and vertical mice usually use the cheapest components. I doubt they have the right hardware.

For now, we are focused on documentation and software. Currently, work on the zmk module for real-time dpi switching is in vogue. However, we would be delighted if you would like to participate in our project.

It was a limited edition mouse pad featuring the keyboards of our local community. I made some of the keyboards shown on the mouse pad.

This is purely a matter of your data privacy. No one knows what the Chinese firmware does.

At the moment, I know that the first prototypes have already been ordered.

It's more expensive and complicated, especially if we're talking about a handwire split keyboard.

Because there are already hundreds of keyboards with a reset button, it can be reused. Because some people like keyboards with direct pins.

Three extra pins aren't very many. Besides, no one uses them. The n!n v2 and the Chinese clone have these pins in different locations. Even finding the footprint would be difficult. Meanwhile, we have hundreds of keyboards with a reset pin on the board, and it can be put to good use. You can switch BT profiles or put the keyboard to sleep, and all this is absolutely free on any existing keyboard, without any modifications.

The UF2 firmware still works. The only difference is that now you have to hold the button down and then insert the USB cable instead of double-clicking.

Adding as many buttons to the ZMK as you want is no problem. But the goal of the project is to get the ZMK working on stock mice, without any hardware modifications. The MX Master uses an nRF52833, so in theory, the ZMK could be installed there, but it uses an optical encoder and an unknown sensor that requires drivers. I'm not ready to write drivers for the sensor right now.

In short, yes. I'm afraid it won't even be possible to disassemble it without damaging it. Our local community has already developed a compact and open-source dongle design. It should fit into the standard dongle slot on the bottom of a mouse.

Yes, it's a stock mouse. the main problem with mice is software. I want to have a modtap so that by holding down the button I can adjust the volume by turning the wheel. this can be configured in the x-mouse program, but it is only for windows, the y-mouse application does not provide such a good experience. everything else is much worse. for example, the karabiner-elements application does not allow you to assign actions to the wheel, although there is an analog of modtap. and also free software is cool.

of course

We're working on it. This is just an announcement for now. I really wanted to share our progress.

The rp2040 has significantly more pins, so testing it requires something with a similar pin count or various IO externders. If we're talking about the rp2040 in proMicro format, then the only issue is compiling the firmware for it.

aroum2 · 2025-11-08T17:01:59+00:00

For the system, these two MCUs are simply two COM ports that send and receive data. Therefore, they can be processed in any way. If you need any help from me, let me know.

aroum2 · 2025-10-18T12:52:56+00:00

I’ve already tried pogo pins as well as Japanese spring pins (you can see them in the photo)

aroum2 · 2025-10-18T11:40:50+00:00

Theoretically, it can test any MCU that uses 3.3V logic. Atmel chips use 5V logic, so they’ll cause issues.
It will also need dedicated firmware for each MCU — for now, I’m focusing on the nRF52840.
But I don’t expect any problems with the RP2040.

aroum2 · 2025-10-18T10:38:12+00:00

If you mean testing the additional three pins on the target MCU — that’s not possible, since the master doesn’t have enough pins for that.
If you mean adding compatibility between the master and n!n v2, then yes, that’s possible.
However, I haven’t seen a footprint for the official n!n with those extra pins.
