Overview

The BTM511 is a low-power Bluetooth module from Laird designed for integrating robust audio and voice capabilities to OEM devices. Based on the market-leading Cambridge Silicon Radio BC05 chipset, these modules provide exceptionally low power consumption with outstanding range. Supporting Bluetooth Version 3.0 specification, these modules provide the important advantage of Simple Secure Pairing (SSP) that improves security and enhances easy use. BTM511 modules come standard with SBC, AAC and apt-X audio codec support for high quality stereo audio applications. 

BTM511 modules are provided with CSR’s apt-X codec without additional license fees. CSR’s world renowned apt-X™ audio compression solutions retain the full integrity of original digital audio and are optimized for instant real-time audio streaming.

To speed product development and integration, Laird has developed a comprehensive AT command interface that simplifies application development, including support for audio and headset functionality. Combined with a low-cost development kit, Laird’s Bluetooth modules provide faster time to market.

Note: The BTM510-xx variant has reached end of production and is available on a limited basis only. Only the BTM510 part numbers are affected. Find the End of Life Announcement in the Documentation tab below.
