This is the Sipeed NanoKVM. You stick it on your computer, plug in HDMI, USB, and the power button, and you get full remote control over the network—even if your computer locks up.
How did Sipeed make it so small, and so cheap? The 'full' kit above is about $50, while the cheapest competitors running PiKVM are closer to $200 and up!
This blog post is a lightly-edited transcript of the following video on my YouTube channel:
tl;dr: Sipeed sent a Lichee Console 4A to test. It has a T-Head TH1520 4-core RISC-V CPU that's on par with 2-3 generations-old Arm SBC CPUs, and is in a fun but impractical netbook/cyberdeck form factor. Here's my video on the Lichee Console 4A, and here's all my test data on GitHub.
Last year I tested the StarFive VisionFive 2 and Milk-V Mars CM—both machines ran the JH7110, a 4-core RISC-V SoC that was slower than a Pi 3.
Sipeed introduced the Lichee Pi 4A line of computers, offering a slightly newer T-Head TH1520 SoC, which is also 4-core, but uses faster C910 cores than the JH7110.
