Overview

The EK-RX261 is the evaluation kit for the RX261 MCU, providing an efficient tool to evaluate the RX261 MCU. This kit comes with all the hardware and software needed to start evaluation immediately after unboxing.

The EK-RX261 enables debugging key functions of the RX261. In addition, it can be connected to various expansion boards quickly to easily expand the board's functionality.

This board features:

  • Hardware and software ready for evaluation right out of the box
    • On-board debugger (E2 OB): program writing and debugging are possible simply by using a USB cable to connect the board to a PC.
    • Ready-to-use software package includes peripheral function drivers, middleware, and guidance documentation.
  • Ability to develop prototypes for a wide range of requirements.
    • On-board popular ecosystem connectors: easily connect to expansion boards such as sensor, wireless, LCD, motor boards, etc., enabling to develop wide range of applications quickly.
    • 2 capacitive touch buttons to evaluate latest touch IP for modern HMI applications.
    • CAN FD, USB Full Speed to develop industrial/building automation application prototypes.
    • Multiple power options to enhance power supply flexibility to meet various needs.

Getting Started

Developing Embedded Application

The software development to evaluate the RX261 MCU’s function can be started immediately using the e2 studio IDE and the RX software package that includes peripheral function drivers, middleware, and usage documentation.

  1. Get familiar with EK-RX261 through the Quick Start example project – The Quick Start example project shows:

    • Communication between EK-RX261 and Host PC through USB to Serial interface
    • Control User LEDs via User Buttons

    Refer to the EK-RX261 Quick Start Guide for details.

  2. Start with one of the application projects – Various sample projects for RX261 are available. These example projects can be downloaded from "Design & Development" and 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-RX261 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-RX261 Design Package.
