SiFive is removing more roadblocks to developers wanting to build applications for its open source RISC-V processor. In March the company raised over $143,000 in a crowdfunding campaign, in which it took pre-orders for HiFive Unleashed, a $999 single-board computer for developers featuring the most powerful RISC-V system-on-a-chip to date, the Freedom U540, a multi-core processor that clocks in at up to 1.5 GHz. Earlier this month, SiFive collaborated with the Southern California-based processor maker Microsemi to sell a limited number of HiFive Unleashed Expansion Boards at $1,999 apiece, or a bundled set that includes the expansion board and the previously offered SBC for $2,998. So far, they’ve sold seven of the expansion boards and four bundled sets, taking in $25,985.
