AT Data Module
BTM410/411
The BTM410 and BTM411 Bluetooth
®
modules from Laird 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 mm 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 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.
A comprehensive AT command interface is included, which simplifies firmware integration.
Combined with a low cost developer’s kit, this ensures that choosing Laird Bluetooth
modules guarantees the fastest route to market.
