RKX-EVK-001 and ROHM EVK EVB 

ROHM EVK HW User’s Guide 

 

The ROHM EVK is an easy-to-use platform that allows evaluation of ROHM products. The evaluation kit is based on the Infineon CY8CKIT-059 

Prototyping Kit featuring an integrated SoC based on the ARM® Cortex®-M3 CPU with powerful analog and digital peripherals. The ROHM EVK 

comes with a highly configurable RKX-A3-EVK-001 that provides an easy-to-use hardware interface between the MCU and the variety of Digital 

ROHM devices in a plug-and-play fashion. Finally, the ROHM EVK GUI SW, a powerful Windows-based desktop application, provides an intuitive 

Graphical User Interface capable of displaying and logging the real-time device data, and configuring the device functions through a graphical 

register editor, to name a few. 

This user guide describes the ROHM EVK HW. For the ROHM EVK SW, please refer to the ROHM EVK SW User’s Guide.
