$59 HiFive1 Arduino Compatible Board is Powered by Sifive Open Source RISC-V MCU (Crowdfunding)

Royalty-free RISC-V instruction sets has been getting in the news in the last few years with various MMU designs from companies or projects like lowRISC, PULPino, and SiFive, and recently there are been rumors that Samsung may use RISC-V in their future IoT SoCs. Many projects are still in progress, and while you can get involved in OnChip Open-V MCU crowdfunding campaign to their get the MCU or a development board, the cost for the MCU ($49) and development board ($99) is a little on the high side, and delivery is expected in 2018 for most rewards. SiFive appears to have a more interesting open source RISC-V solution with HiFive1 Arduino compatible board going for $59 and slated to ship between December 2016 and February 2017. HiFive1 development board specifications: MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) Storage – 128 Mbit […]

OnChip Open-V Open Source 32-bit RISC-V Processor Launched on CrowdSupply

Open source hardware gives mostly full control over software and hardware, but there are different levels of openess, with some companies wrongly claiming their product to be open source hardware – with a nice accompanying logo – once they dump some source code somewhere and publish the PDF schematics, while others are doing it right with the release of schematics and PCB layout in source format, as well as software and proper documentation. However even for the latter group, the actual chips are closed source bought directly from silicon vendors or their distributors. So the good news is that you now have the opportunity to bring the meaning of open source hardware to a whole new level thanks to OnChip Open-V 32-bit  processor that is open source, and getting launched on Crowd Supply crowdfunding platform. OnChip Open-V is based on RISC-V (pronounced “risk-five”), comes with peripherals, and should be competitive […]
