GR-PEACH is the Gadget Renesas board for the Renesas RZ family's RZ/A1H group of microprocessors (MPU) products. Fully pin-compatible with Arduino UNO, GR-PEACH is an ARM® Mbed™ enabled development platform. GR-PEACH takes advantage of web browser-based program development and a robust library selection. With the added appeal of 10MB of built-in RAM and the processing power of ARM Cortex™-A, GR-PEACH was created for the developer interested in high-speed prototyping of IoT devices with loads of HMI—graphics, touch panel, camera input, audio, network and more.

In addition, RZ/A1H FreeRTOS™ Software Package for GR-PEACH has been released.


In addition, GR-PEACH supports multiple platforms, .NET Micro Framework (MF), Arduino, and TOPPERS/ASP (RTOS). Click the platform figures below to be directed to the respective getting started pages.

Project File for e2 studio

Project file for sketching in Eclipse-based development environment e2 studio. For downloading and installing e2 studio, please refer to the e2 studio product page.

You can import as an archive file (zip) as an existing workspace from the e2 studio menu "File" -> "Import".

Do the menu "Project" -> "Update all dependencies" at the initial build. Only sources changed since the next build will be compiled.


DisplayApp is an application that displays the camera image sent by USB CDC.

Installing the USB driver is required on versions earlier than Windows 10.

Below is an Arduino-like sketch example.

#include <Arduino.h>
#include <Camera.h>
#include "DisplayApp.h"
Camera camera;
static DisplayApp display_app;
void setup() {
void loop() {
    display_app.SendJpeg(camera.getJpegAdr(), (int)camera.createJpeg());
