Getting Started with Renesas RX65N Cloud Kit

The Renesas RX65N Cloud Kit is a cloud communication performance evaluation kit that uses the RX65N microcontroller and can connect via Wi-Fi to Amazon Web Services (AWS). It provides an ideal evaluation environment for developers and supports the start of IoT device development by users.

The kit includes a Wi-Fi communication module, a temperature/humidity sensor, an optical sensor, a 3-axis accelerometer, a USB port for serial communications, and another USB port for debugging. The sensor and other data that is uploaded from the kit to AWS can be observed in the dashboard. The program can also be edited or debugged in Renesas' e² studio integrated development environment (IDE), by connecting the kit to a PC.
