This cheap RISC-V board runs Debian and is an essential part of my smart home
The Milk-V Duo S is a RISC-V-based SBC, and with Wi-Fi and Bluetooth, it's incredibly useful.

Nearly a year ago, I first got my hands on the Milk-V Duo S, an SBC with two RISC-V cores and an Arm core. You can use a slider to switch between the two modes when booting, though it wasn't possible to boot off the Arm core at first. The company has put out updates and released new bootable images, including an image that can boot from its Arm core. Over time, many community members built their own images based on RISC-V for the Milk-V Duo S as well.
