HiFive1 Rev B

SiFive launched what may have been the very first RISC-V development board in 2016 thanks to their HiFive1 Arduino compatible board powered by Freedom E310 (FE310) open source RISC-V processor. The company has now launched an upgrade version of the processor and board. Meet FE310-G002 processor and HiFive1 Rev B development board. HiFive1 Rev B development board specifications with new features highlighted in bold or stricken-through: MCU – SiFive Freedom E310-G0002 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) Storage – 32 Mbit SPI flash (was 128 Mbit in the first version) Connectivity – ESP32-SOLO-1 WiFi & Bluetooth module I/Os 19x Digital I/O Pins 19x external interrupt pins 1x external wakeup pin 9x PWM pins 1/3 SPI Controllers/HW CS Pins I/O Voltages –  3.3V or 5V supported; note: bidirectional level shifters removed so FE310-G002 can drive the I/O pins directly at 3.3V only. USB – 1x micro USB […]
