SiFive announced the Arduino Cinque, the new RISC-V based development board | Open Electronics

The Arduino Cinque is the second RISC-V based development board put out by SiFive (the first being the HiFive1) compatible with the Arduino platform. “By partnering with a pioneer in open-source hardware, SiFive can further advance the progress of open custom silicon”

Board has SiFive’s Freedom E310 customizable SoC, which runs off the E31 CPU Coreplex (32-bit RV32IMAC Core): the Freedom E310 claims to be the fastest microcontroller on the market, capable of running at 320 MHz.

The Arduino Cinque will also have built-in Wi-Fi and Bluetooth capabilities with the inclusion of an efficient, low-power Espressif ESP32 Wi-Fi/Bluetooth hybrid chip.

    A Smaller, Cheaper RISC V Board

    Early this year, the world of electronics saw something amazing. The RISC-V, the first Open Source microcontroller was implemented in silicon, and we got an Arduino-derived dev board in the form of the HiFive 1. The HiFive 1 is just a bit shy of mindblowing; it’s a very fast microcontroller that’s right up there with the Teensy when it comes to processing power. There’s support for the Arduino IDE, so all those fancy libraries are ready to go. That’s not to say there aren’t a few problems; it’s a relatively expensive board, and it does use the ubiquitous but somewhat unfortunate Arduino form factor.

    . Meet the LoFive RISC-V. It’s a GroupGets crowdfunding campaign from [Michael Welling], and it takes all the openness from the HiFive 1 and the FE310 microcontroller and stuffs it into a cheap, easy-to-use board.
