    Overview

    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.

    Features

    • Bluetooth® v2.0+EDR

    • Adaptive Frequency Hopping to cope with interference from other wireless devices

    • External or internal antenna options

    • Comprehensive AT interface for simple programming

    • Bluetooth® END Product Qualified

    • Compact size

    • Class 2 output – 4dBm

    • Low power operation

    • UART interface

    • PCM and SCO for external codec

    • GPIO lines under AT control

    • Support for multiple profiles

    • Wi-Fi co-existence
