What are the key features of the BMD-345-A-R?
The u-blox BMD-345-A-R is a 2.4 GHz wireless transceiver module that supports Bluetooth® 5.0, IEEE 802.15.4, Thread, and Zigbee® communication protocols. It comes in a compact surface-mount package with a U.FL connector for an external antenna. The module integrates radio and protocol stacks, reducing the need for additional components and simplifying design. Its multi-protocol support enables flexible deployment across different wireless network types.
What is it used for?
This module is used to add reliable short-range wireless connectivity to embedded and IoT devices. Typical applications include smart home systems, sensor networks, industrial monitoring, lighting control, asset tracking, and other products that require Bluetooth or mesh networking (Thread/Zigbee) communication. Its low power consumption and compact size make it suitable for battery-powered and space-constrained designs.
Does it have alternative parts?
Yes, alternative modules with similar multi-protocol support are available from u-blox (e.g., BMD-3 series variants) as well as other manufacturers such as Silicon Labs, Nordic Semiconductor, and Texas Instruments. When selecting an alternative, ensure the device supports the required protocols (Bluetooth/802.15.4/Thread/Zigbee), has compatible form factor, and meets your performance and power requirements.
