Overview

The RA2E3 Fast Prototyping Board comes equipped with an RA2E3 MCU and is an evaluation board specialized for prototype development for a variety of applications. It has a built-in SEGGER J-Link™ emulator circuit so you can write/debug programs without additional tools. In addition, it includes Arduino Uno™ and Pmod™ interfaces as standard, along with through-hole access to all pins of the microcontroller, offering high expandability.

Sample software is available to demonstrate the functionality of the RA2E3 MCU and to facilitate connections between the RA2E3 Fast Prototyping Board and various wireless or sensor modules.

Please use Bluetooth® and LoRa®, etc. according to the radio regulations of each country during use.
