In this video, we take a look at the Banana Pi BPI-RV2, a compact single-board router powered by a RISC-V processor. If you haven't heard of RISC-V before, it's an open-source processor architecture that is gaining serious traction in the SBC and networking space, and this board is a great example of why. Built around the SiFlower SF21H8898 SoC, it packs a 4-core 64-bit RISC-V CPU, a hardware NPU with L2 and L3 offloading, 20 gigabit switching capacity, a 2.5GbE WAN port, PoE support, NVMe and Wi-Fi expansion via M.2, and even a nano SIM slot - all in a small, wall-mountable form factor with an optional case.
We walk through the hardware, cover how to flash OpenWRT 25.12.2 (the first stable release that actually works on this board, only available since March 2026), and set it up from scratch using the serial console, UCI commands, and LuCI. I also cover some gotchas around finding the right firmware file, fixing network access post-flash, and getting WireGuard installed for a site-to-site VPN setup. This is a great little open-source router board for homelab use, small business networking, or anyone wanting proper hardware offloading without spending a fortune.
