Renesas Electronics EK-RA4M3 Evaluation Kit for RA4M3 MCU Group

Added to your shopping cart

Renesas Electronics EK-RA4M3 Evaluation Kit enables users to easily evaluate the features of the RA4M3 32-Bit Microcontroller (MCU) Group. Users can develop embedded systems applications using the Flexible Software Package (FSP) and e2 studio Integrated Development Environment (IDE). The included EK-RA4M3 Board features a pre-mounted RA4M3 MCU, two USB ports (debug and Full Speed), a wide range of expansion options, and headers providing direct access to pin signals.

The Renesas Electronics RA Flexible Software Package (FSP) provides a quick and versatile way to build secure connected IoT devices using the Renesas RA Family of Arm microcontrollers. FSP provides production-ready peripheral drivers, FreeRTOS, and middleware stacks to take advantage of the FSP ecosystem.

e² studio is an Eclipse-based integrated development environment (IDE) for Renesas MCUs. In addition to Eclipse’s own powerful code editor, the e² studio offers a rich range of extended functions. The e² studio covers all development processes, from the downloading of sample code to debugging.
