Introduction

SparkFun is pleased to welcome a whole new instruction set architecture (ISA) to its family, the RISC-V ISA (pronounced “risk-five”), and along with it, introduce the RED-V RedBoard (pronounced “red-five”). In this tutorial, we'll be focusing on the hardware.

"The force is strong with this one." (Star Wars: A New Hope, 1977)

What sets the RISC-V ISA from the rest is that it is completely open-source; including the instruction set architecture (ISA). That means anyone can make full use the microcontroller without requiring royalties, licenses, or non-disclosure agreements (NDAs). The RED-V comes in the familiar Arduino Uno form factor 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, and a Qwiic connector.

Required Materials

To follow along with this tutorial, you will need the following materials and software. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary. Here is what you would need to get started:

  • RED-V - You'll definitely need this; otherwise, you are probably on the wrong tutorial page (wink).
  • USB 3.1 Cable A to C - 3 Foot - The USB interface serves two purposes: it powers the board and allows you to upload programs to it. (You might even have a few of these in you drawer!)

Segger Programmers

If you would like to debug or flash your processor on your own, here are some of our SEGGER Programmers. We also recommend getting the 1.27mm header pins with some jumper wires to connect. Depending on the programmer that you use, you may need to use a combination of wire wrap and IC hooks to connect.
