So are RISC-V chips already available? Or is it that the chips available are all low power things.
I'm curious how much effort is left, before it's possible to build an open source PCB that those who wanted to could send off to be printed and populated, which could serve as some kind of MVP motherboard.

- leggomylibro 7y agoGD32VF103 chips are similar to STM32F103s and you can get boards with them for ~$5: https://www.seeedstudio.com/Sipeed-Longan-Nano-RISC-V-GD32VF103CBT6-Development-Board-p-4205.html https://www.seeedstudio.com/Sipeed-Longan-Nano-RISC-V-GD32VF... Kendryte K210 modules are a bit more expensive, but they include an "AI coprocessor" which looks like a sort of SIMD accelerator. They come in creepy "camera+wifi" form factors for all of your dystopian facial recognition needs: https://www.seeedstudio.com/Sipeed-M1w-dock-suit-M1w-dock-2-4-inch-LCD-OV2640-K210-Dev-Board-1st-RV64-AI-board-for-Edge-Computing-p-3207.html https://www.seeedstudio.com/Sipeed-M1w-dock-suit-M1w-dock-2-... And if you're willing to spend a bit more, SiFive also sells "Freedom" boards which are more like SBCs than microcontrollers: https://www.sifive.com/boards https://www.sifive.com/boards
- ColanR 7y agoVery cool. It looks like there is a board like what I was imagining, 1.5GHz quad core + 8GB DDR4 RAM, but it's not for sale anymore. Limited run crowdfunding. The design files and schematics are available, though, so I guess it's possible to get the boards built. Thanks for the links.
