Renesas Electronics RL78/G1x Fast Prototyping Boards are evaluation boards that are equipped with RL78/G1x microcontrollers. These MCUs are a new product in the RL78 microcontroller family that specializes in application prototyping. These prototyping boards consist of a built-in emulator circuit that is equivalent to an E2 emulator Lite to write/debug programs without additional tools. The RL78/G1x fast prototyping boards are equipped with an Arduino Nano header that helps in using the interface without modifying the hardware. Additionally, debugging is easy with the Arduino Nano header and with combined use function that provides access to all pins of the target microcontroller.
