MUSE Book laptop review – Testing an octa-core RISC-V Linux laptop in 2026

SpacemiT sent me a sample of the MUSE Book RISC-V Linux laptop for review. It’s based on the SpacemiT K1/M1 octa-core 64-bit RISC-V SoC, ships with up to 16 GB of RAM, eMMC flash and/or NVMe SSD, and features a 14.1-inch IPS display with 1920×1080 resolution, WiFi 6 connectivity, a few USB ports, and more. I won’t go through all the hardware specifications since Leo already did that when he wrote about the MUSE Book Laptop in April 2024, along with a teardown, and additional details about the SpacemiT K1/M1 SoC. I’ll still do an unboxing and quickly check the hardware, but I’ll focus on the software part to show the progress with Bianbu OS 2.3 (Ubuntu 24.04-based) on RISC-V hardware, as I just did for the low-end StarFive JH7110S-based VisionFive 2 Lite SBC. It’s quite a long review, so if you are short on time, you can jump directly […]

VisionFive 2 Lite SBC Review – Ubuntu 24.04 on a low-cost RISC-V SBC in 2026

VisionFive 2 Lite RISC-V SBC Ubuntu Review 2026

StarFive has sent me a sample of the VisionFive 2 Lite RISC-V SBC for review. It’s a low-cost credit card-sized board based on the StarFive JH7110S quad-core RISC-V SBC and designed to get started with Linux RISC-V on the cheap. When I first tested the earlier VisionFive 2 SBC with a StarFive JH7110 RISC-V SoC in February 2023, I didn’t call it a review, but rather a hands-on experience, since, at the time, many features still didn’t work properly. Almost three years have passed since then, so reviewing the VisionFive 2 Lite SBC with Ubuntu 24.04 will allow us to see how much progress has been made on the software side. If you are in a rush, you can jump to the what works, what doesn’t section. VisionFive 2 Lite unboxing I received the board in a plastic box with a cover reading “VisionFive 2 Lite Your Gateway to RISC-V”. […]
