What 400kb of RAM on an MCU?! That's a huge amount for an MCU. Arduino's started out with 2kB of SRAM. Linux also requires a MMU to run, which most's MCU's don't have.
- josephg 5y agoThanks; but I don’t want an MCU. I don’t even know what an MCU is. Arduino style devices aren’t interesting to me. I want something I can run Linux, like a raspberry pi but RISC-V. I know there were some bigger development boards out there for $600+ a few years back. Is there anything in the pipes which is smaller, for hobbyist messing around?
- goosedragons 5y agoThere is at least one now called the Sipeed Nezha, costs about $115 on Aliexpress with 1GB RAM. Seems like it's similar to an older RPi.
- josephg 5y agoOh thanks for pointing me in the right direction. It looks like they're now shipping $20 development boards with their new chips in the Sipeed LicheeRV. 512MB of ram and linux support: https://www.aliexpress.com/item/1005003594875290.html https://www.aliexpress.com/item/1005003594875290.html
