Overview

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.

Note: This board comes with two touch buttons and one slider using a capacitive sensor unit for simple evaluation, but when designing an actual board, please check the Capacitive Sensor Microcontrollers CTSU Capacitive Touch Electrode Design Guide (R30AN0389) and use the Capacitive Touch Evaluation System for RL78/G22 (RSSK-RL78G22) for evaluation.
