Overview
Description
The RA0E2 Fast Prototyping Board comes equipped with an RA0E2 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 RA0E2 MCU and to facilitate connections between the RA0E2 Fast Prototyping Board and various wireless or sensor modules.

- Where to find BSDL files for RA0 family
Hi, does anyone know where to obtain BSDL/SVD files for the RA0 microcontroller family? We are using Segger Ozone with the FPB-RA0E2 board and it would be very helpful to see all peripherals. With best regards, Ewout Boks
