The following are the technical characters of a Bluetooth device:

The devices are either a one chip solution or multiple chips in general. Blue tooth device has three main parts – RF, baseband processor and link manager (COULD be a CPU core like 8 or 16 bit REDUCED Instruction SET Computer. A BT module in multiple chips, usually 2 or 3 chip, like RF on a chip are produced by certain vendors.

For a single chip solution, the following information can be used for referencing from a particular vendor.

• Package : 81 ball BGA, 8mm x 8mm
• Supply Voltage : 2.7 – 3.3v
• Power Consumption : Data transmitting @ 4dBm – type 41mA
• Voice Only Connection : 15mA for HV3 packets, 30mA for HV1
• RI Page Scanning : 420uA
• Inquiry Scanning + RI Page Scanning : 560uA
• Park mode (1 second interval) : 120uA
• Standby state : 10uA

The components, the chip, memory and the crystal, antenna could be placed on a PCB about 20mm x 15mm. The thickness of the chip is about 1.25mm or 1.55 mm..
