The BTM510 and BTM 511 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 the latest Bluetooth Version 2.1+EDR specification, these modules provide the important advantage of secure simple pairing that improves security and enhances easy use.

Only 14mm x 20mm, the compact size makes it ideal for battery-powered or headset form factor audio and voice devices. With a 16-bit stereo codec and microphone input to support both stereo and mono applications, these modules also contain a full, integrated Bluetooth-qualified stack along with SPP, HFP 1.5, HSP, AVRCP, and A2DP profiles. (Customers using these modules may list and promote their products free of charge on the Bluetooth website.)

The BTM510/511 modules include an embedded 32-bit, 64-MIPS DSP core within the BC05. Integrated Bluetooth functionality 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.

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.
