Description
The RED-V Thing Plus comes programmed with a simple bootloader. The modern USB-C connector makes it easy to program over USB connectivity or use as a JTAG interface via the FE310's NXP K22 ARM Cortex-M4. Since the Thing Plus footprint is also Feather-compatible, you can take advantage of existing shield options. We have included a Qwiic connector to enable future use of our handy plug-and-play I²C Qwiic Connect System, which means no soldering or shields are required*. With so much freedom & growing industry functionality, the SparkFun RED-V Thing Plus is an ideal choice for your RISC-V project.
The onboard Freedom E310 (FE310) is the first member of the Freedom Everywhere family of customizable SoCs from SiFive. Designed for a microcontroller, embedded, IoT, and wearable applications, the FE310 features SiFive’s E31 CPU Coreplex, a high-performance, 32-bit RV32IMAC core. Running at 150MHz, the FE310 is among the fastest microcontrollers in the market. Additional features include a 16KB L1 Instruction Cache, a 16KB Data SRAM scratchpad, hardware multiply/divide, a debug module, flexible clock generation with on-chip oscillators, PLLs, and a wide variety of peripherals, including UARTs, 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 RED-V Thing Plus requires Freedom Studio software or a Zephyr RTOS build environment to program the board and interface with it.
