How I discovered a hidden microphone on a Chinese NanoKVM

>>ementa+(OP)
To be fair, the microphone _is_ listed on the specsheet of the LicheeRV Nano

I assume they didn't intend to put a mic on the KVM product, but they wanted to make a KVM product, already had this SBC product, which reusing their existing stock of helped keep cost low.

Should they have been more up front about it it? Sure, and it's not great that they had a bunch of security issues in the FW anyway, so not exactly great, but "hidden microphone in a Chinese KVM" lets the mind wander

The Chinese part makes one think the Chinese could access the microphone.

Nevermind that, if they could access the device, they'd also be able to read your kvm i/o.

You might be right but I think we cannot assume malice when it could be laziness. It might be that the exact same board has multiple target audiences and they just rebrand it for different purposes with different pricing.

That said, the microphone is so weirdly positioned that it gets suspicious indeed.

Why can't it be both?
