GR-PEACH is the GR reference board for RZ family RZ/A1H group 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 high-speed prototyping of IoT devices with loads of HMI -- graphics, touch panel, camera input, audio, network and more!


In addition GR-PEACH supports multiple platform .NET MF, Arduino, TOPPERS/ASP(RTOS), so you can program with these platform. Click the below figure and then jump to the page getting started.
