A2235-H Overview

Small footprint The power pins, ground pins, and dedicated pins are at the same pin location across device densities so it can adapt to your actual configuration.
Ultra Low power consumption SiRFaware’s advanced low power management modes, high level of integration and multiple communication ports in a small form-factor makes the A2235-H suitable for a broad spectrum of GPS applications where performance, cost and time to market are prime considerations (only 29 mA average tracking).
Anti-jamming detection Our receivers offer an anti jamming feature: they constantly scan the signals in the area and blank out the non-satellite ones. You are then safe from jammers and others interferences.
