Overview
The EK-RA2A2 evaluation kit enables users to effortlessly evaluate the features of the RA2A2 MCU group and develop embedded system applications using Renesas' Flexible Software Package (FSP) and e2 studio IDE. Utilize rich on-board features along with your choice of popular ecosystem add-ons to bring your big ideas to life. The kit includes the EK‑RA2A2 v1 board and a micro USB device cable (Type‑A male to micro‑B male).
Getting Started
Running the Quick Start Example Project
- The EK-RA2A2 board comes pre-programmed with a quick start example project (source code provided in the EK-RA2A2 example project bundle).
- Power up the EK-RA2A2 board through the USB debug port (J10) using the micro USB device cable connected to a 5V power source. The white power LED will light up.
- The Quick Start example project will begin to execute by blinking the blue user LED.
- Refer to the EK-RA2A2 – Quick Start Guide to explore additional functionality of the quick start example project.
Developing Embedded Applications
- Modifying the quick start example project – refer to the EK-RA2A2 Quick Start Guide for instructions on importing, modifying, and building the quick start example project.
- Start with one of the many other example projects (provided in the EK-RA2A2 example project's bundle) – choose from many example projects to learn about different peripherals of the RA2A2 MCU group. These example projects can be excellent starting points for developing your custom applications.
Building Custom Hardware
- Start by building a functional prototype - utilize the EK-RA2A2 board with your choice of ecosystem add-ons.
- Build custom hardware – develop custom hardware by referring to the design and manufacturing information provided in the EK-RA2A2 design package.
