The BTM410 and BTM411 Bluetooth® modules from Laird are designed to meet the needs of developers who
wish to add robust, short range Bluetooth data connectivity to their products. These modules are based on the
market leading Cambridge Silicon Radio BC04 chipset, providing exceptionally low power consumption with
outstanding range. They support the Bluetooth® version 2.1 specification, providing the important advantage
of Secure Simple Pairing (SSP), which improves security and ease of use for end customers.
With physical sizes as small as 12.5 mm x 18.0 mm 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. They can then list and promote products on the Bluetooth website free of charge.
A comprehensive AT command interface is included, which simplifies firmware integration. Combined with a
low cost developer’s kit, choosing Laird Bluetooth modules guarantees the fastest route to market.
