The BTM510 and BTM511 are low-power Bluetooth® modules designed for adding robust audio and voice

capabilities. Based on the market-leading Cambridge Silicon Radio BC05 chipset, these modules provide

exceptionally low power consumption with outstanding range. Supporting Bluetooth v3.0 specification, these

modules provide the important advantage of secure simple pairing that improves security and enhances easy

use.

At only 14 mm x 20 mm, the compact size of the BTM510 is ideal for battery-powered or headset form factor

audio and voice devices. With a 16-bit stereo codec and microphone inputs to support both stereo and mono

applications, these modules also contain a full, integrated Bluetooth-qualified stack along with SPP, HFP 1.6,

HSP, AVRCP v1.5, and A2DP profiles.

The BTM510/511 modules include an embedded 32-bit, 64-MIPS DSP core within the BC05. This is integrated

with the Bluetooth functionality which allows designers to add significant product enhancements including

features such as echo cancellation, noise reduction, and audio enhancement using additional soft codecs. The

availability of the 16MB of flash memory in the module allows complex functionality to be included. DSP

routines can be licensed through a number of specialist partners. Typical applications for these modules include

Bluetooth stereo headsets, VoIP phones, and wireless audio links.

To speed product development and integration, Laird Technologies has developed a comprehensive AT

command interface that simplifies application development, including support for audio and headset

functionality. Access to GPIO pins allows mapping for direct connection to actuator buttons on headsets.

Combined with a low-cost development kit, Laird Technologies’ Bluetooth® modules provide faster time to

market.
