Overview

The BMD-300-A-R is a highly integrated Bluetooth 5.0 Low Energy module based on the Nordic Semiconductor nRF52832 SoC. It features an Arm Cortex-M4F processor with 512kB of flash and 64kB of RAM, providing a complete RF solution with an onboard trace antenna and DC-DC converter. This module is globally pre-certified for FCC, CE, and other international standards to simplify wireless product development.

Why Choose This Part

This module reduces time-to-market by including an integrated antenna and full regulatory certifications. Its high-performance Cortex-M4F core allows for complex local processing, while the efficient power management system offers significant current reductions when using the internal DC-DC converter.

Applications

Industrial Sensor Networks
Uses Bluetooth mesh and high sensitivity (-96dBm) to maintain robust connections in factory environments.
Wearable Health Devices
Leverages the ultra-low 0.3uA shutdown current and 3.3mA CPU execution current for extended battery life in portable electronics.
Smart Home Automation
Utilizes 32 GPIO pins and a 12-bit ADC to interface directly with sensors and actuators without an external MCU.
Asset Tracking
Provides LE 2M PHY support for higher data throughput and efficient Over-the-Air firmware updates in logistics applications.
