Overview

The BMD-350-A-R is a high-performance Bluetooth 5.0 module based on the Nordic Semiconductor nRF52832 SoC. It integrates a 64MHz Arm Cortex-M4 CPU with a floating-point unit, 512kB of flash memory, and an onboard trace antenna into a compact 6.4mm x 8.65mm footprint. This module is designed for power-efficient wireless applications requiring sophisticated processing and minimal external components.

Why Choose This Part

The module's main advantage is its extreme integration, featuring a built-in DC-DC converter and trace antenna that eliminate the need for complex RF layout work. Its low power consumption of 5.3mA during 0dBm transmission and a sub-microamp sleep mode significantly extend battery life for remote endpoints.

Applications

Bluetooth Mesh Networking
Utilizes the high memory capacity and Bluetooth 5 hardware support to manage complex mesh node operations in smart lighting and industrial automation.
Wearable Health Monitors
The ultra-low 0.3uA standby current and integrated FPU make it ideal for battery-operated devices performing local sensor fusion.
Industrial IoT Sensors
Leverages the hardware AES encryption and -96dBm sensitivity for secure, long-range telemetry in harsh RF environments.
