Overview
Description
The RL78/G23-128p Fast Prototyping Board, featuring the RL78/G23 microcontroller, is ideal for various prototype developments. It supports AWS cloud connectivity via the Wi-Fi DA16600 module, OTA firmware updates, 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 Mega, Pmod™, and Grove interfaces, access to all microcontroller pins, and high scalability. It includes two touch buttons using a capacitive sensor unit, unique to RL78/G23. Renesas also provides an Arduino library that supports creating various programs (sketches) on the Arduino IDE.
Note: This board comes with two touch buttons 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/G23 (RSSK-RL78G23) for evaluation.
A 64-pin board is also available: RL78/G23-64p Fast Prototyping Board
