Love this. Not sure why nobody responded...
this is awesome to use. Wireless M/K with a retro rig? No problemo.

I got one. It's nice, especially if you have a spare Pi 3 that you are looking to repurpose, but I'd prefer something a little less bulky and that fits inside a case.

USB4VC shows up mentioned in other threads. Main problem is ridiculous price forced by using full rpi. Its way over $100 after adding Protocol Card/cables/power supply/SDcard for something doable with $5 pico 🙁 Those:
mice/keyboard

provide same functionality at 1/3-1/6 the cost without added complexity of a whole Linux computer running in the background (>30 seconds boot time before your keyboard starts working).
USB4VC is great at what it does. Rpi made it super flexible and easy to develop, but rpi pricetag and up to recently rpi supply shortages made it not that attractive.

USB4VC is great in my opinion. Easy to assemble, doesn't look like a hack job at the end. It's only missing a proper enclosure! It's the only thing missing for it.
HIDman above looks like a good solution and the end product is very good looking. Same with the PicoGUS. But these lack the "everything" USB4VC offers as a one device to rule them all.

I appreciate the costs are high, but I'm very willing to pay to not have the hassle of having to assemble it all myself (for sure if I did I would end up with a non working device at the end!)

yeah. not everybody enjoys all the "fun" of buying all the parts and assembling the crap by himself... you only trade your money with your time.
having said that, I have a USB4VC, I'm glad that somebody else did it for me and it does exactly what it's supposed to do

I picked one up as part of the Kickstarter along with the extra cables etc. It's already paid for itself just going through my stack of old machines.

Thread resurrection~~~

Yeah, there's no arguing that using a full Raspberry Pi for this is a little much. That said, as others have mentioned it does exactly what it says on the tin. Its big advantage over other solutions is Bluetooth support, not just for mouse/KB but also modern PS/XBox controllers, etc. It also has a companion app to create controller or game-specific profiles, so you can assign custom keyboard or mouse actions to your controllers. Its little OLED display allows for switching out these profiles, changing mouse/KB protocols, etc.

Really, it's very flexible but probably overkill for a lot of applications. I'm def going to check out HIDman so I have something when all I really need is simple mouse/kb.

Just for reference, I'm not running off of a full pi. I just slapped one of my Pi zero Ws on there and it works just fine.
