SiFive Shifting Production Focus To Next-Gen HiFive Development Board
SiFive Shifting Production Focus To Next-Gen HiFive Development Board

SiFive's HiFive Unmatched is the best, readily available RISC-V developer board at the moment with enough horsepower for modest development/porting work and continues seeing improvements with the mainline Linux kernel. But availability on HiFive Unmatched is beginning to dry up and SiFive isn't planning on any further production runs as it begins focusing on the board's successor.
