Bluetooth Module
BTR310

The BTR310 module is a complete Bluetooth® solution for fast implementation, cutting your time-to-market. It is a short-range, compact and cost effective radio/baseband module that can be implemented in any kind of electronic devices.

In standard configuration the module includes a baseband processor with on board 8Mbit Flash memory, a radio front-end, antenna interface, supporting circuitry, together with some higher-level software protocols and applications such as L2CAP, SDP, SPP, HSP and HFP are resided in the Flash.

The BTR310 module is a power class 2 Bluetooth® device, and is in compliance with version 2.0 EDR of the Bluetooth® specification. It is supplied with Bluetooth® protocol stack firmware which runs on the internal microprocessor. The BTR310 module is built on CSR BC04 External core with an 8Mbit Flash memory for firmware and application software storage.
