GNSS receiver comes in 7 x 7 mm package

November 22, 2013 // By Julien Happich
In a 7 x 7 x 1.1 mm LGA module, the u-blox EVA-7M integrates all the necessary components, including crystal and passives, to support US GPS, Russian GLONASS, Japanese QZSS and all SBAS augmentation systems. It only requires an antenna for global positioning capability.

The module has a sensitivity of -160 dBm when tracking GPS satellites (-158 dBm with GLONASS satellites), a fast acquisition time, and draws 6.5 mA at 3V thanks to a high-efficiency power converter. The EVA-7M is a standalone GNSS receiver which provides a position without the need for host integration or extra RF components. It is optimised for keeping eBOM and system costs to an absolute minimum.

A UART, USB, SPI and I 2C interface provide flexible connections to a host processor. EVA-7M can also communicate directly with u‑blox’ SARA 2G, LISA 3G and TOBY LTE cellular modules to support advanced tracking and location-aware applications.
