Modular embedded wireless solution

New from Sequoia Technology are a range of surface mountable, 27mm-square shielded RF modules developed by Norwegian low power radio specialist Bluechip Communication.

New from Sequoia Technology are a range of surface mountable, 27mm-square shielded RF modules developed by Norwegian low power radio specialist Bluechip Communication.

The range comprises two modules for operation at 433 and 868MHz respectively, optimised for ultra-low power consumption, easy design-in, low-cost and small size.

Potential applications include wireless local networking, two-way paging, telemetry, environmental control systems, personnel or patient logging, access and movement monitoring, remote meter reading and barcode readers.

The units are fully assembled and tested with all HF components, and zero-ohm matching to an external antenna, onboard.

Driver software for the onboard microcontroller is also included in the solution.

Minimal external components are required for full operation, and only four digital I/O lines are needed.

Supply voltage range is 2.5 to 3.3V.

Evaluation kits for 433 and 868MHz modules are also available to shorten development time, featuring external RF/onboard loop connections and onboard software.

The kits include onboard socketed microcontroller, RS-232 interface, external RF/onboard loop connections and onboard software.

Test modes including RF parameters, auto two-way communication and data byte transfer are selectable via dipswitches.

At typical output power of 10mW in the 433MHz version and 7mW in the 868MHz version, each evaluation board typically consumes 45mA.

A sub-1uA power down mode is also provided.
