Laird Technologies (St. Louis, MO) has introduced a range of Bluetooth® modules designed to support the demands of medical equipment manufacturers. Designed for data applications, the BTM411 is a fully integrated, sub-miniature Bluetooth data-oriented module based on Cambridge Silicon Radio's BC04 chipset. Incorporating a full Bluetooth stack and supporting a serial port profile, the module provides a UART interface and comprehensive AT command set to allow easy interface to a host processor.

For medical products that require DSP applications, the BTM520 series offers a wide range of functions including a high-gain, multilayer ceramic antenna that provides +10dBm output for multimedia requirements. The integrated Bluetooth stack provides a comprehensive range of profiles. The 32-bit Kalimba DSP, running at 64MIPS, allows onboard implementation of a variety of advanced applications.

The modules are based on the latest Bluetooth standard, Version 2.1+EDR, and deliver Secure Simple Pairing. This allows for simpler user interfaces that make products easier to use and, subsequently, reduces support costs. Designed for high reliability, these modules support an industrial operating temperature range of -30ºC to +70 ºC.
