Overview

Description

The RL78/G22 Fast Prototyping Board, featuring the RL78/G22 microcontroller, is ideal for various prototype development. It supports OTA firmware updating of a secondary MCU, Wi-Fi, LoRa and LoRaWAN-based wireless communication, and so on by sample code. The built-in emulator circuit that is equivalent to E2 emulator Lite allows programming and debugging without extra tools. Additionally, it has Arduino Uno and Pmod™ interfaces, access to all microcontroller pins, and high scalability. It includes two touch buttons and one slider using a capacitive sensor unit, unique to RL78/G22. Renesas also provides an Arduino library that supports creating various programs (sketches) on the Arduino IDE.
