HiFive1 Rev B

Based on the success of the SiFive HiFive1 and developer feedback, the SiFive HiFive1 Rev B is an Arduino-compatible development board featuring the SiFive Freedom E310-G002 (FE310-G002) SoC plus a ESP32-SOLO-1 Wi-Fi and Bluetooth module, making it the best way to prototype and develop RISC-V software for IoT and embedded applications. Designed for IoT and edge computing, the FE310-G002 instantiates a SiFive Essential™ E3 Series CPU Core Complex, a high performance 32-bit RV32IMAC core. Additional features include a 16KB L1 Instruction Cache, a 16KB Data SRAM scratchpad, hardware multiply/divide, a debug module compatible with the RISC-V debug spec 0.13, flexible clock generation with on-chip oscillators and PLLs, and a wide variety of peripherals including UARTs, I2C QSPI, PWMs, and timers. Multiple power domains and a low-power standby mode ensure a wide variety of applications can benefit from the FE310. The USB debugger has been upgraded to SEGGER J-Link-OB, adding support for drag & drop flash programming as well as SEGGER JLink integration with SiFive Freedom Studio, an Eclipse based IDE. Freedom Studio is packaged with a prebuilt toolchain and example software projects. Alternatively, the SiFive Freedom Tools download package includes a pre-built toolchain, debugger, and additional command line tools that can be plugged into your own bespoke development environment.
