Overview

The 453-00039-K1 is a development kit for the Ezurio BL653 module, which is based on the Nordic Semiconductor nRF52833 SoC. It provides a complete prototyping environment for Bluetooth 5.1, Thread, Zigbee, and NFC applications using an ARM Cortex M4F core with 512KB Flash and 128KB RAM. The board features an integrated PCB trace antenna and allows for full evaluation of the module's low-power capabilities and peripheral interfaces.

Why Choose This Part

The board supports a wide operating voltage of 1.7V to 3.6V and features a highly efficient DC-DC converter that reduces peak Tx current to 14.2 mA at +8 dBm. Its multiprotocol radio allows simultaneous support for BLE and 802.15.4, making it an ideal bridge between different IoT ecosystems.

Applications

Asset Tracking
Utilize Bluetooth 5.1 Direction Finding (AoA/AoD) and long-range coded PHY for precise location services in industrial environments.
Smart Building Automation
Implement multiprotocol concurrency with Thread and Zigbee for secure, mesh-networked lighting and climate controls.
Professional Lighting
Leverage high temperature ratings and robust 802.15.4 radio support for commercial DALI or Zigbee lighting systems.
Medical Wearables
Develop ultra-low power health monitors using the 0.6uA deep sleep mode and integrated NFC for easy device pairing.
