Overview
Description
EK-RA6W2 was designed to help us overcome the real challenges of building low-power, secure wireless IoT systems faster and with confidence. By combining a powerful main board with a wireless & Bluetooth® LE daughter card, we enable seamless software development, RF performance evaluation, and cloud connectivity testing on a single platform. Our integrated power measurement circuitry allows us to precisely analyze current consumption, even in low-power sleep modes, so we can optimize battery life early in the design cycle. With microBUS™, Pmod™, and Arduino® Uno connectors, we make it easy to expand, prototype, and validate complete systems using real-world peripherals—all while reducing development risk and time to market.
Features
