Overview

The EK-RA2A1 evaluation kit enables users to effortlessly evaluate the features of the RA2A1 MCU Group and develop embedded systems applications using Renesas' Flexible Software Package (FSP) and various IDEs.

Getting Started

Running the Quick Start Example Project

  1. The EK-RA2A1 board comes pre-programmed with a quick start example project (provided with the example projects bundle).
  2. Power up the EK-RA2A1 board through the USB debug port (J11) using the micro USB device cable connected to a 5V power source. The green power LED will light up.
  3. The quick start example project will begin to execute blinking the red user LED.
  4. Refer to the EK-RA2A1 Quick Start Guide to explore additional functionality of the quick start example project.

Developing Embedded Applications

  1. Modifying the quick start example project – refer to the EK-RA2A1 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 RA2A1 MCU group. These example projects can serve as excellent starting points for you to develop your custom applications.

Building Custom Hardware

  1. Start by building a functional prototype - utilize the EK-RA2A1 board with your choice of ecosystem add-ons.
  2. Build custom hardware – develop custom hardware by referring to the design and manufacturing information provided in the EK-RA2A1 v1 - Design Package (ZIP | English, 日本語)
