The Renesas Electronics fast prototyping board comes equipped with an RL78/G23 microcontroller and is an evaluation board specialized for prototype development for a variety of applications. It has a built-in emulator circuit that is equivalent to an E2 emulator Lite so you can write/debug programs without additional tools. In addition, it comes standard with Arduino Mega, and PmodTM and Grove interfaces, has access to all pins of the microcontroller, and is highly scalable.It is equipped with two touch buttons utilizing a capacitive sensor unit, which is one of the features of the RL78/G23.
