Keychron announces first open-source firmware for gaming mice (digitalfoundry.net)

A bit ago I accidentally bought a Keychron keyboard that didn't have QMK support, but then found that someone had ported it anyway, and I was able to flash it and fix some problems I had (the main one being that it seems like the default firmware only scans a single row of keys while asleep, possibly to save energy, but I want any keypress to wake the computer.) Maybe it's not perfect, but the community around open source keyboard firmware is great, it's a good example of how open source is beneficial for end users, especially power users.

And, in an era where vendor software and firmware for all kinds of devices is constantly having vulnerabilities, it is possible the liability of doing custom shit will eventually outweigh whatever benefits hardware companies seem to think it has, versus just having industry standards and free software instead. But, maybe that is wishful thinking.

My only complaint with Keychron is that of 5 or so keyboards I've owned from them I wound up having to resolder 3 different hotswap sockets on 2 different keyboards right out of the box. That is... Not a fantastic failure rate. OTOH, they are otherwise an unambiguously great value, with materials and build quality that feels pretty impressive for the cost, QC issues notwithstanding.

My only complaint is that the backlight behavior has like a dozen different settings, none of which are "off". There's "on", "flicker", "blink when you hit the key", "ripple out when you hit the key", "move in waves regardless of input", etc., but there's no "don't be light" option.

I bought a K4 Nordic version, only to learn none of their software supports it. So i can't reconfigure the firmware.

The keyboard has swapped Super/Alt (Windows/Alt) on the windows layout which is so annoying. I hate spending money on hardware so i'm living with it, but i curse the engineer that burned the prom every day.

That sucks, the main reason I like KeyChron is the little switch on the side of mine that toggles between Mac and Windows! I wouldn't buy another keyboard without this feature TBH.

Why not reconfiguring it with something like AutoHotkey at the OS level ?

spike021 2 hours ago

my issue with the one i have (k2, iirc) is that if i use it wirelessly and the battery dies, it becomes a brick until its been fully recharged. it won't even work as a wired keyboard until then. so ever since then i only use it wired.

Hmm, I have a mouse and trackballs from ploopy, they run QMK, so why was a new project needed? What is the added value?

To me, the missing feature in the QMK ecosystem is a devices too device communication channel. For now there is only caps lock & others: it would be nice to activate a mouse layer (for instance: increase DPI) to a keyboard key.

It is probably solvable if a heavyweight was to push for new HID descriptors or something similar.

Announces != releases.

They claim 2027 Q1 will be the release date.

Links below purporting to be “the repository” lead to a repo with no source code.

Sorry, I’m cynical. An announcement 6-9 months ahead of release? Why? Right now it’s vaporware.

ssl-3 an hour ago

I'm cynical, too, and I have good reason to be.

I recently bought a Keychron TKL keyboard that uses Hall effect switches. It is, in my opinion, a lovely board to type on and so far I like it quite a lot. (Hopefully, this board with its socketed HE switches will serve longer than the previous board that had soldered Cherry MX Blues.)

It was advertised as being open-source and supporting QMK. Not at some time in the mysterious future, but right then. (And that's still true right now -- the web page is unchanged.)

But it does not have source available. The link for source code on the website lands at a Github page for a completely-unrelated keyboard, and I can't do anything at all with it using QMK. Extensive digging to find the source has resulted in zero positive results.

In the case of this Keychron keyboard, the promise of source code consists of resolute lies more than it does vaporware: The source is stated to openly exist, but it does not exist.

A question about this situation to their support email resulted in assignment of a ticket number, followed by silence.

So yeah, anyway: The cynicism is valid.

bluGill 2 hours ago

Keychron is a real company with a good history so it isn't unreasonable to expect it and thus you shouldn't be too cynical. However don't confuse that with don't be cynical at all - many companies with a good history have canceled projects, and this is still vaporware.

If they plan on developing it in the open and taking early contribution / feedback could be a valid (and good) reason.

jerlam 3 hours ago

This would be more exciting if Keychron had mice of more interesting / experimental form factors and functionality. Just like their keyboards, their mice are mostly differentiated by obscure technical features (polling rates!).

I'm a bit worried that a decent, modern replacement for the extremely obsolete multi-button mouse I have now (Logitech G602) will never be available.

russianGuy83829 2 minutes ago

While its not on the same level, check out the M6. You can remap the side scroll buttons, as well as the two other ones, which gives you four actions.

i'm using this mouse for over 2 years now: https://happort.org/mouse

it uses this board: https://github.com/jfedor2/rp2040-pmw3360 and i can dig into my .stl files for the mouse if you want... made it on Blender and https://ryanis.cool/cosmos/beta - it's not the most lightweight thing in the world (would say around 100 grams) but it slides nicely and maybe by cycling/exercising often i don't think this one would give me RSI at any point in time... it's angle based on the most muscle neutral position the human arm anatomy has, between 20° - 30° [0] https://www.jospt.org/doi/pdf/10.2519/jospt.2004.34.10.638

I miss my G602 so much. Replaced it with a G604 and then replaced that one with another G604 and then a third G604 before realizing that Logi's build quality has seemingly dived off a cliff for the premium they charge for their product and swapped to the 50% as expensive Keychron mice and keyboards and have been satisfactorily living with the decrease in available buttons (though quite an adjustment was needed). Onset of carpal tunnel has seen me switch to a vertical mouse anyways, so a change was inevitable.

My G602 died due to Logitech's infamous double-click issue. :(

I've been fine with the G502 X Lightspeed (which should avoid said double-click issue due to optical switches) and some more efficient button use to compensate for the fewer side buttons.

What's wrong with the G502? I like the wired G502 pretty well. Ideally I'd tweak the shape to be a little more like the M500s shape, but I'm happy enough with it overall.

pdpi an hour ago

I had a G502 that lasted years, but the last two I bought lasted me 6 months each (the wheel got completely gummed up somehow). I acknowledge that cat hair and sweaty hands are a bad combination for a mouse wheel, but that's insanely poor durability, and they're annoying enough to disassemble that they're effectively not cleanable.

Yep!

> This repository is currently in its early setup phase.

> At the moment, the repository mainly contains project scaffolding, policy files, and the initial project direction. Firmware sources, board support, build instructions, and flashing guidance are still being prepared.

> That means zgm is early, but it is intentionally early in public. The goal is not to wait until everything is finished before opening the door. The goal is to make the long-term direction visible and let the project grow into a useful open firmware platform in the open.

Hopefully better than their QMK fork. They force push over their branch in their fork each new release effectively erasing history of the last version...

Of course there's no change log anywhere either...

Does that mean they remove any release tags as well?

I don't blame them though. QMK is a mess of a monolithic repository.

QMK should be thrown away. ZMK is much, much cleaner.

I bought a Q6 wired keyboard. Most solid keyboard I've ever owned.

Only problem is the backlight didn't actually light up the keys.

It wasn't fixable. first, the keys that came with the keyboard were opaque. And after the arduous task of replacing the keys with shine-through keycaps -- all the LEDs were positioned below the keystem instead of above, so the lettering wasn't illuminated.

I would have loved to use that keyboard. Switched to steelseries apex pro.

I really wanted to like Keychron, but after spending 200$ on one of their high end keyboards, certain keys weren't detecting presses less than a month later. I couldn't end up fixing it so I tossed it out. Felt like a waste

zamadatix an hour ago

Same. I ended up resoldering nearly all of the contact points (i.e. not the hot swap contact points but where those connect to the main board) because I liked the keyboard and firmware so much but it was such a stupid problem (way too little solder from the factory) for such an otherwise good and high end keyboard.

abhinavk an hour ago

I am deep into custom keyboards but I only buy ones with hot swappable switches. Some keys like AWSDEHJKL etc are bound to fail sooner than others.

The mechanical keyboard hobby takes patience; just look at firmware customization: testing litterally requires keystrokes.

I'm on a Mac keyboard bent for the very reason, actually,

Mouse firmware sounds very cool, though. If you could access a layer by holding down a central button, that could open up neat possibilities.

fwip 39 minutes ago

And all of us have owned multiple keyboards that have lasted for years of daily heavy use without a single key failing. Even the $30 membranes you could buy at $local_retailer didn't fail in a month.

theGeatZhopa 2 hours ago

Hmm that opens up a way for cheating in games - have a Screengraber and image processing running directly communicate with mouse and let it calculate the distance to region of interest internally and then give out delta position. For the system, it looks like the mouse has been moved very fast and far

orbital-decay 2 hours ago

There's a ton of low-latency proxy hardware meant for cheating that does exactly that, out of the box, for those too lazy to do it themselves on any devboard. It's not an excuse for closed source mouse firmware

kllrnohj 2 hours ago

it's hardly difficult to do that already. Like a Raspberry Pi Pico can be turned into a HID mouse rather easily: https://www.instructables.com/Raspberry-Pi-Pico-As-HID-Mouse...

and yes, hdmi/displayport capture -> ML object detection -> fake HID mouse to cheat is absolutely already a thing.

Graziano_M 2 hours ago

It's already being done. The fanciest game hacks use a custom PCI card to DMA game memory, read it on another computer, where it can do wallhacks and such.

But also, the second computer can drive a virtual mouse and keyboard which is connected to the 'legit' PC to even aim/move/shoot for you.

I’ve had positive experiences with Keychron products in the past, but I’ve moved past them as I now prefer orthogonal layouts. That said, I loved their support of QMK on my Q1 Pro and I really hope this ends up on that same level.

I stumbled upon this brand when I was looking for a hall effect QMK keyboard.

Glad to see them introducing this - I might make a purchase as while my current mouse is great, I can't customise it because the associated bloatware runs only on Windows.

userbinator an hour ago

Never have I thought "I want a mouse with modifiable firmware", IMHO this is only going to lead to more bugs arising from the associated increase in complexity and the "we can always fix it later" mentality. All the mouses and keyboards I've used have a mask-programmed MCU, and essentially no bugs to speak of.

rincebrain an hour ago

I think the point is less to add features and more to lower the barrier to entry for people making mice, since, as you said, in large part keyboards and mice are appliances to the degree that it should rapidly converge to a stable set of features.

Plus, on a human level, I wouldn't be surprised if the teams working on mouse development were annoyed they couldn't show their past work in the same way...

matchstickman23 3 hours ago

Very interesting. I've been eyeballing a mouse/trackball project for a while based on some of the open source designs like Ploopy and the like. Slap a Nordic chip on it and a joycon battery. Even better if you can cook up a wireless charging mousepad like Logitech offers!

I suspect that a lot of hardware will start shipping open source firmware soon. Routers, IP cameras, etc.

It'll be a selling point for everyone tinkering with vibe coding, and it's no longer a moat.

Companies that don't do this will have their firmwares dumped with open source models and tools. Companies that do this will have community goodwill and extra distribution that comes from having people talking about your product.

kube-system 3 hours ago

That might happen in niche enthusiast verticals like PC gaming. It's not going to happen in the broader market because there is no broader interest in it.

Most people want open source firmware for their router like they want open source sewing patterns for their pants. Primarily these are consumer products where people buy the product as a way to intentionally avoid spending time dealing with the problem they solve.

Open source pants might sell well in a Hobby Lobby and an open source IP camera might sell well in a Micro Center, but neither would sell well enough to get shelf space in a Walmart... and the best selling one in Walmart sells a tiny fraction compared to whoever can land an Xfinity contract.

Those already exist: OpenWRT, OpenIPC. I wish more hardware was available though, especially for cameras.

loloquwowndueo 3 hours ago

Do you have any cameras that support openipc you’d recommend?

I need surveillance cameras (outdoor mostly) but the cheap ones I found are a horrid proprietary mess. I even bought and returned one after the setup was complex and invasive.

Basically all I need is access to the live stream from a raspberry pi where I can store and process the video.
