New from Laird Technologies are the enhanced BTM410/411 and BTM420/421 Bluetooth radio modules. The devices are designed for data applications and are fully integrated, sub-miniature Bluetooth data-oriented modules based on a market leading chipset. Incorporating a full Bluetooth stack and supporting serial port profile (SPP), the modules provide a UART interface and a comprehensive AT command set to allow an easy interface to a host processor.
The Bluetooth modules support the latest BT2.1 + EDR, SSP, SPP, SCO and eSCO specifications, and also meet FCC/IC/CE standards. With physical sizes as small as 12,5 x 18,0 mm and low-power operation, they are suitable for applications where designers need both performance and miniature size. For flexibility in systems integration, the modules are designed to support a separate power supply for I/O.
The BTM410 supports an external antenna whereas the BTM411 incorporates an onboard, high-performance ceramic chip antenna. The modules are fully qualified as Bluetooth end products, allowing designers to integrate them within their own products with no further Bluetooth qualification. The BTM420/421 modules use the same sub-miniature format, but support a USB HCI interface and are pre-approved as Bluetooth controller subsystems. The BTM420 module supports an external antenna whereas the BTM421 module incorporates an onboard, high-performance ceramic chip antenna.
