SiFive Learn Inventor RISC-V Development Board

SiFive rolled out an educational development board using their third generation RISC-V core MCU FE310-G003 mainly targeting students, hobbyists, makers. Looks like the edge interface is inspired by BBC Micro:bit board. SiFive is the same company which launched the HiFive1 board with their first ever silicon using RISC-V processor.

SiFive is a leading provider of market-ready processor core IP and silicon solutions based on the free and open RISC-V instruction set architecture. Led by a team of seasoned silicon executives and the RISC-V inventors, SiFive helps SoC designers reduce time-to-market and realize cost savings with customized, open-architecture processor cores, and democratizes access to optimized silicon by enabling system designers in all market verticals to build customized RISC-V based semiconductors.
