Google announces official Android support for RISC-V
Over the holiday break, the footage from the recent "RISC-V Summit" was posted for the world to see, and would you believe that Google showed up to profess its love for the up-and-coming CPU architecture? We've been trying to nail down how the Android team feels about RISC-V (reduced instruction set computer) for a while. We last heard a comment from the team six months ago, where our Google I/O q
StarFive VisionFive 2 quad-core RISC-V SBC launched for $46 and up (Crowdfunding) - CNX Software
StarFive VisionFive 2 quad-core RISC-V SBC launched for $46 and up (Crowdfunding) As expected, StarFive has officially unveiled the JH7110 quad-core RISC-V processor with 3D GPU and the VisionFive 2 SBC. I just did not expect the company to also launch a Kickstarter campaign for the board, and the version with 2GB RAM can be had for just about $46 for “early birdsâ€. The VisionFive 2 ships with up

Pine64's RISC-V Ox64 Takes On Raspberry Pi Pico W
The Raspberry Pi Pico W has a new competitor in the form of Pine64’s upcoming Ox64, spotted by CNX Software, which uses the increasingly popular RISC-V architecture to pack a lot of computing power into a tiny space. So much, in fact, that it's starting to blur the boundaries between microcontrollers and SBCs. (Image credit: Pine64)There's been no official announcement, the company hasn't tweeted
World's First Laptop with RISC-V Processor Now Available
