for a
Connected
World
The BTM410 and BTM411 Bluetooth
®
modules from Laird Technologies have been designed
to meet the needs of developers who wish to add robust, short range Bluetooth data
connectivity to their products. They are based on the market leading Cambridge Silicon
Radio BC04 chipset, providing exceptionally low power consumption with outstanding
range. They support the latest Bluetooth Version 2.1 Specification, providing the important
advantage of Secure Simple Pairing, which improves security and enhances the ease of use
for end customers.
With a footprint as small as 12.5 x 18.0 mm for the BTM410 and best of class, low-power
operation, these modules are the ideal choice for applications where designers need both
performance and minimum size. For maximum flexibility in systems integration, the modules
are designed to support a separate power supply for I/O.
To aid product development and integration, Laird Technologies has integrated a complete
Bluetooth protocol stack within the modules, including support for the Bluetooth Serial Port
Profile. The modules are fully qualified as Bluetooth End Products, allowing designers to
integrate them within their own products with no further Bluetooth Qualification. They can
then list and promote their products on the Bluetooth website free of charge.
A comprehensive AT command interface is included, which simplifies firmware integration.
Combined with a low cost developers kit, this ensures that the choice of Laird Technologies
Bluetooth modules guarantees the fastest route to market.
