The EK-RA6M3G evaluation kit enables users to seamlessly evaluate the features of the RA6M3 MCU Group and develop embedded systems applications using Renesas' Flexible Software Package (FSP) and e2 studio IDE. You can utilize rich on-board features along with your choice of popular ecosystem add-ons to bring your big ideas to life.

The EK-RA6M3G kit consists of two boards: the EK-RA6M3 board featuring the RA6M3 MCU with on-chip graphics LCD controller and the graphics expansion board featuring a 4.3-inch TFT color LCD with capacitive touch overlay.

Getting Started

Running the Quick Start Example Project

  1. The EK-RA6M3G comes pre-programmed with Quick Start example project (Provided with the example projects bundle).
  2. Connect the graphics expansion board to the graphics expansion port (J1) on the EK-RA6M3 board.
  3. Power up the EK-RA6M3G 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.
  4. The Quick Start example project will begin to execute showing graphics elements on the screen.
  5. Refer to the EK-RA6M3G – Quick Start Guide (PDF) to explore additional functionality of the Quick Start example project.

Developing Embedded Applications

  1. 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 for the RA6M3 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-RA6M3 and graphics expansion boards 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-RA6M3Gv1 - Design Package (ZIP | English, 日本語)
