SparkFun will be closed on Monday, May 30th, for Memorial Day. We will resume normal business hours at 9am (MT) on Tuesday, May 31st. Orders placed after 2pm (MT) on Friday May 27th will process and ship out on Tuesday, May 31st. From all of us at SparkFun, we wish you a safe and happy Memorial Day weekend!
The SparkFun RED-V (pronounced “red-five”) Thing Plus is a low-cost, development board in our popular Thing Plus footprint and adds in the Freedom E310 core and RISC-V instruction set architecture (ISA). What sets the RED-V Thing Plus apart is the completely open-source approach from hardware to ISA. That means anyone can make full use the microcontroller without requiring royalties, licenses, or non-disclosure agreements.
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 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. 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 and 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 set up to program the board and interface with it.
Note: Please be aware that Qwiic Libraries are not yet available for the Freedom Studio SDK or the Zephyr environment that runs on the FE310. We will update the community when these become available.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Expert - You should be extremely comfortable programming on various hardware in several languages.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
