Getting Started

Running the Quick Start Example Project

1. Power up the EK-RA4W1 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.
2. The Quick Start example project will begin to execute blinking the red user LED.
3. Refer to the attached EK-RA4W1 Quick Start Guide (bin file are included) to explore additional functionality of the Quick Start example project.

Developing Embedded Applications

1. Modifying the Quick Start example project – Refer to the EK-RA4W1 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 – Choose from many example projects to learn about different peripherals of the RA4W1 MCU group. These example projects can serve as an excellent starting points for you to develop your custom applications.

Building Custom Hardware

1. Start by building a functional prototype - Utilize the EK-RA4W1 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-RA4W1 design package.
