Intel PBA31308 UniStone Bluetooth Module

Intel PBA31308 UniStone Bluetooth Module

Intel’s PBA31308 UniStone Bluetooth Module is a fully integrated Bluetooth® device including stack and Serial Port Profile (SPP) for data transfer applications, with an easy command interface enabling easy design-in and minimal host requirements. This high performance module offers outstanding range and efficient utilization of low power modes. It is compliant to BT 2.0 plus enhanced data rate and is equipped with a powerful ARM7TDMI processor. The low-cost system requires no external components except the antenna. The small module offers a small solution footprint.
