Overview
Description
The EK-RA6W1 is a comprehensive development kit consisting of a main board and daughter card. This configuration facilitates easy software application development, providing tools and resources that simplify the process of writing and testing code. The EK-RA6W1 also supports RF (radio frequency) testing, allowing developers to measure and optimize performance, as well as evaluate how their developments integrate with cloud services. A unique feature of this kit is the integrated power profiler circuit, which enables power consumption measurements during low-power sleep with precision down to 1µA. To support full software application development and system validation, the EK-RA6W1 offers multiple expansion options, including mikroBUS™, Pmod™, and Arduino® UNO connectors. These standardized interfaces make it easy to add sensors, displays, etc. to EK-RA6W1.
