A Smaller, Cheaper RISC V Board

Posted on by

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 …read more

Arduino Cinque – The RISC-V, ESP32, WiFi, Bluetooth Arduino

Posted on by

This weekend at the Bay Area Maker Faire, Arduino in conjunction with SiFive, a fabless provider of the Open Source RISC-V micros, introduced the Arduino Cinque. This is a board running one of the fastest microcontrollers available, and as an added bonus, this board includes Espressif’s ESP32, another wonderchip that features WiFi and Bluetooth alongside a very, very powerful SoC.

Details on the Arduino Cinque are slim at the moment, but from what we’ve seen so far, the Cinque is an impressively powerful board featuring the RISC-V FE310 SoC from SiFive, an ESP32, and an STM32F103. The STM32 appears to …read more
