Overview

The EK-RA6M3 evaluation kit enables users to seamlessly evaluate the features of the RA6M3 MCU Group and develop embedded systems applications using the Flexible Software Package (FSP) and e2studio IDE. Utilize rich on-board features along with your choice of popular ecosystem add-ons to bring your big ideas to life.

Getting Started

Running the Quick Start Example Project

  1. The EK-RA6M3 comes pre-programmed with a quick start example project (provided with the example projects bundle).
  2. Power up the EK-RA6M3 board through the debug USB port (J10) using the micro USB device cable connected to a 5V power source. The white power LED will light up.
  3. The quick start example project will begin to execute blinking the red, green and blue user LEDs.
  4. Refer to the EK-RA6M3 – Quick Start Guide (PDF) to explore additional functionality of the quick start example project.

Developing Embedded Applications

  1. Modifying the quick start example project – refer to the EK-RA6M3 Quick Start Guide for instructions on importing, modifying, and building the quick start example project
  2. Start with one of the many other example projects (provided in the example projects bundle) – choose from many example projects to learn about different peripherals of the RA6M3 MCU Group. These example projects can serve as excellent starting points for you to develop your custom applications.

Building a Custom Hardware

  1. Start by building a functional prototype – utilize the EK-RA6M3 board with your choice of hundreds of popular ecosystem add-ons.
  2. Build custom hardware – develop custom hardware by referring to the design and manufacturing information provided in the EK-RA6M3 v1 - Design Package (ZIP | English, 日本語)
