Easily add Bluetooth connectivity to products

12 July 2006 Telecoms, Datacoms, Wireless, IoT

Embedded class 1 and class 2 Bluetooth modules that can quickly change your serial communications to Bluetooth wireless are now being offered by UK company Kanda (www.kanda.com).

The modules have a low pin count, easy configuration and a small profile. The 3,3 V Serial to Bluetooth modules can be built-in to any product to give a powerful Bluetooth connection, without any fuss or knowledge of Bluetooth, according to the company.

They provide a simple Bluetooth node for system installers, instrument engineers and product designers, or anyone who uses serial communications in their product. These 8- or 12-pin DIL modules are simply fitted on the PCB, the serial lines connected to the module and an instant Bluetooth Interface is created, says Kanda.

There are two module types for Class 1 and Class 2 Bluetooth - the main difference being the signal range. Class 2 modules are 8-pin with an onboard antenna and a range of 30 metres. Class 1 modules have 12 pins. They use an external antenna with a 15 cm extension cable, and have a range of 100 metres.
