Overview
Description
The EK-RZ/A3M evaluation kit enables users to easily evaluate the features of the RZ/A3M MPU. This kit includes an EK-RZ/A3M board, 5-inch 720x1280 pixel LCD MIPI graphics expansion board, and USB cables, allowing the seamless evaluation of high-definition human machine interface (HMI), camera input through USB, and more features. Equipped with an on-board J-Link debugger, users can conveniently start debugging without additional debuggers. Additionally, it also has several expansion connectors such as SDIO, PMOD, and Arduino to connect sensors, Wi-Fi, and Bluetooth® Low Energy (LE), allowing users to add more features without expanding the board space.
