Raspberry Pi Grants Remote Access Via PCIe (Sort Of)

[Jeff] uncovered a Raspberry Pi — well, the compute module variation, anyway — in an odd area: on a PCI Convey card. Why would you plug a Raspberry Pi into a Pc? Nicely, you are not particularly. The card makes use of the PCI Specific connector as a way to mount in the personal computer and hook up to the PC’s floor. The Pi exposes its own community cable and is run by PoE or a USB C cable. So what does it do? It presents distant keyboard, online video, and mouse (KVM) expert services. The trick is you can then get to the Computer system remotely even if you need to have to accessibility, say, the BIOS set up screen or troubleshoot an OS that won’t boot.

This isn’t a new strategy. In fact, we have observed the fundamental Pi-KVM software right before, so if you never brain figuring out your mounting selections for a Raspberry Pi, you likely do not want this board. Excellent thing way too. Judging by the remarks, they are really hard to actually acquire — probably, due to the chip lack.

Although it would seem seductive to have a distant resolution that does not count on fiddly software program — or even what working program you are employing — [Jeff] notes that latency is relatively superior, so you possibly will not be joyful with it for any gaming or online video. But that’s not really what it is for.

It did make us consider, even though. The PCI Convey has 12V and 3.3V electrical power and ground connections. Some motherboards even provide 3.3V when the laptop or computer is off. What else could you mount inside of the laptop with just one of these matters? Or what else could you do with this Pi card? Networked USB it’s possible?

We’ve viewed a Pi get surgical procedure to contain a PCI bus, as well. Or, you can opt for the easier surgical approach. While plugging one particular of these KVM boards into a modified Pi would be pointless, we also feel it would be amusing.
