Bluetooth Modules Function in Embedded Designs
Laird Technologies, Inc. announces four Bluetooth modules that incorporate Bluetooth stacks, and they are pre-approved to minimize the design effort in implementing short range wireless. The BTM410 for data applications is a fully integrated, sub-miniature Bluetooth data-oriented module based on Cambridge Silicon Radio's BC04 chipset. Targeted at systems running an embedded operating system with its own Bluetooth stack (such as Windows CE or Linux), the BTM420 module range uses the same sub-miniature format, but it supports an HCI interface. Suitable for audio and multimedia applications, the BTM510 module supports headset applications, and it is based on Cambridge Silicon Radio's BC05 chipset with integrated DSP. It includes a full Bluetooth stack with built-in support for A2DP, AVRCP, HFP and HSP profiles. For power multimedia applications, the BTM520 series offers a high-gain, multilayer ceramic antenna that provides 10 dBm output.
