The BTM430 and BTM431 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. With a footprint as small as 12.5 x 18.0 mm for the BTM430 and best of class low-power operation these modules are the ideal choice for applications where designers need both performance and minimum size.
Note: The BTM430-xx variant has reached end of production and is available on a limited basis only. Only the BTM430 part numbers are affected. Find the End of Life Announcement in the Documentation tab below.
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 their products on the Bluetooth website free of charge . A comprehensive AT command interface is included which simplifies firmware integration. This ensures that the choice of Laird Bluetooth modules guarantees the fastest route to market. Available in BTM430 and BTM431 variants.
