The Ezurio BTM402 BISM II module from TDC is a fully qualified Bluetooth version 2.0 solution with a range of up to 1km, that gives developers a drop-in communications solution.

TDC has released a Bluetooth module with an open-field range of 1km from its internal antenna, the longest range of any Bluetooth module.

The range can be further extended by adding high gain directional antenna.

The Ezurio BTM402 BISM II module from TDC is a fully qualified Bluetooth version 2.0 solution with a range of up to 1km, that gives developers a drop-in communications solution requiring minimal integration and no type approval.

According to TDC, Bluetooth devices normally have a range of just 10m, rising to 300m for high-performance modules.

The new Ezurio module should allow many new applications to benefit from the use of this stable and well-recognised standard.

Developed specifically for battery-powered applications, the Ezurio module from TDC supports low-power modes, including a sniff mode where consumption is just 2.5mA.

In full operation, the module draws 130mA from a 3.6 - 5V DC source.

Its size of just 25 x 35 x 8mm further facilitates implementation in portable systems.

Key features of the BTM402 include generous I/O provision for connection to other system resources.

These include nine general-purpose I/O ports, two 8bit analogue input lines and three PCM audio channels.

The module is pin and format-compatible with Ezurio 802.11 WLAN modules, allowing developers to implement Bluetooth and Wi-Fi versions of a product using the same board.

The Ezurio BTM402 BISM II PA Bluetooth Serial Module is a fully integrated and qualified Class 1 Bluetooth solution with RF, baseband, antenna and protocol stack.

The module incorporates the CSR BlueCore 04 chipset.
