RA2E1 fast prototyping board comes equipped with a R7FA2E1A93CFM microcontroller and is an evaluation board specialized for prototype development for a variety of applications. It has a built-in emulator circuit equivalent to an E2 emulator Lite so you can write/debug programs without additional tools. In addition with Arduino Uno and Pmod™ interfaces included standard and through-hole access to all pins of the microcontroller and so on, it has high expandability.
