1 OVERVIEW AND KEY FEATURES
The BTM420 and BTM421 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 and
who are using embedded Bluetooth stacks within 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 with EDR (Enhanced Data Rate). As well as
increasing data throughput up to 2.1 Mbps, this provides the important advantage of Secure Simple Pairing,
which improves security and enhances the ease of use for end customers.
With physical sizes as small as 12.5mm x 18.0mm and best of class, low power performance, 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 separate power supplies for
I/O and the USB interface.
These modules present an HCI interface through a USB interface and are fully qualified as Bluetooth
Controller Subsystem Products. This allows designers to integrate them existing pre-approved Bluetooth Host
and Profile subsystem stacks to gain a Bluetooth END product approval for their product.
A low cost developer’s kit is available for prototyping. This ensures that the choice of Laird Technologies
Bluetooth modules guarantees the fastest route to market.
