St. Louis, Mo.-based Laird Technologies has added four new Bluetooth modules to its line. The four modules incorporate Bluetooth stacks and are pre-approved to minimize the design effort in implementing short-range wireless.

The BTM410 is designed for data applications and is a fully integrated, sub-miniature Bluetooth data-oriented module based on Cambridge Silicon Radio’s BC04 chipset. The BTM410 provides a UART interface and a comprehensive AT command set to allow an easy interface to a host processor. 

Targeted at systems running an embedded operating system with its own Bluetooth stack (such as Windows CE or Linux), the BTM420 module uses the same sub-miniature format, but supports an HCI interface and is pre-approved as a Bluetooth controller subsystem.

Designed for audio and multimedia applications, the BTM510 module supports headset applications and is based on Cambridge Silicon Radio’s BC05 chipset with integrated DSP. Its small form factor with optimized power consumption supports stereo speakers with on-board speaker drivers, as well as a microphone. 

The BTM510 includes a full Bluetooth stack with built-in support for A2DP, AVRCP, HFP and HSP profiles. An AT command set, enhanced for multimedia applications, provides simple control, including the ability to map local switch functionality to a range of I/O pins.

For power multimedia applications, the BTM520 series offers every function designers require, including a high-gain, multilayer ceramic antenna that provides +10dBm output for multimedia requirements.

All these new modules are based on the latest Bluetooth standard, Version 2.1+EDR, and deliver the advantages of secure simple pairing. Development kits and tools are available for all of these wireless modules.
