STMicroelectronics' SPBT2632C1A/SPBT2632C2A micro-sized Bluetooth v3.0 modules offer advanced Bluetooth technology on a highly reliable and affordable platform. The modules are fast, with high data throughput, flexible - offering several serial interface options, and small, coming in a micro-sized form factor (10 mm x 13 mm footprint). The SPBT2632C1A/SPBT2632C2A modules represent an easy to use, cost-effective, standalone solution for users requiring a simple wireless link by establishing a wireless bridge between your device and any other Bluetooth-enabled device. The micro-sized Bluetooth Modules come with different types of serial interfaces (fast UART, SPI, I²C). They can be used in applications such as notebook PCs and accessories, PDAs, access points and industrial controls, as well as for portable medical equipment.
