The SparkFun RED-V (pronounced “red-five”) Thing Plus is a low-cost, development board featuring the Freedom E310 SoC which brings with it the RISC-V instruction set architecture (ISA). The on board Freedom E310 (FE310) is the first member of the Freedom Everywhere family of customizable SoCs from SiFive. Designed for microcontroller, embedded, IoT, and wearable applications, the FE310 features SiFive’s E31 CPU Coreplex, a high-performance, 32-bit RV32IMAC core. Capable of running at 150MHz, the FE310 is among the fastest microcontrollers in the market.
The RED-V Thing Plus comes in popular Feather compatible footprint and includes the SiFive Freedom E310 core, 32MB of QSPI flash, an NXP K22 ARM Cortex-M4 for USB connectivity and operating as a JTAG interface. The RED-V requires Freedom Studio software or a Zephyr RTOS build environment set up to program the board and interface with it.
