Bluetron™ Application Specific Module
BTR310

The Bluetron™ BTR310 module from AvantWave 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, such as hands-free car kit, portable hands-free application, etc.

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 Bluetron™ 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. Bluetron™ BTR310 module is built on CSR BC04 External core with an 8Mbit Flash memory for firmware and application software storage.

Configuration

The BTR310 is based on the scalable Bluetron™ architecture. This configuration allows embedded stand-alone BluetoothR® applicatvvvions where your target application is embedded within the module, in addition to traditional host-based applications. This possibility is especially useful in automotive applications after market and car kit applications. The variety of external interfaces also makes the BTR310 ideally suited for access applications in automotive car kit, high-end USB dongle and mobile computing environments.

Antenna Interface

50Ω Bluetooth ISM Band antenna (2.4-2.5 GHz)


Communication Interface

Communication is carried out using a wide range of external interfaces like high-speed UART, SPI, USB (Universal Serial Bus), I2C, PCM and PIO.


Software

The standard software includes Bluetooth protocol layers up to the HCI-layer or RFCOMM-layer.

In addition, a variety of Bluetooth stacks for host- and embedded applications with different configuration could be offered. Please contact with our sales representatives at sales@avantwave.com or call us directly at 852-2648-9887.
