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.

Features

  • Equipped with an RL78/G22 16-bit microcontroller (48-pin, ROM: 64KB, RAM: 4KB)
  • Programs can be written and debugged via the COM Port communication by connecting it to a PC with a USB cable
  • Able to access all the microcontroller pins
  • Comes standard with Arduino Uno, Pmod™ and Grove interfaces
  • Arduino library available
  • Equipped with capacitive touch sensor buttons
  • Support for various RL78 software and tools

RL78 Family Secondary Device OTA Update Solution

This video will show the steps to operate the secondary device OTA firmware update solution via primary device with the AWS Cloud, tailored for low-end microcontrollers lacking direct internet connectivity.

The evaluation environment uses Renesas' RL78/G22 Fast Prototyping Board and Cloud Kit Based on RX65N (CK-RX65N).
