Swiss-based u-blox has unveiled smallest standalone GNSS positioning module in the market. The LGA module EVA-7M, measuring 7 x 7 x 1.1 mm integrates crystal and passives and need only an antenna for instant global positioning capability.
The module supports US GPS, Russian GLONASS, Japanese QZSS, plus all SBAS augmentation systems. Based on u-blox’ advanced GNSS technology u‑blox 7, the module achieves -160 dBm sensitivity when tracking GPS satellites (-158 dBm with GLONASS satellites), fast acquisition time and the lowest power of any u-blox 7 module (16.5 mA at 3 V) thanks to an innovative high-efficiency power converter.
The EVA-7M eases implementation in end-products because RF and digital domains are kept well separated, and the LGA pads are configured in single rows. Unlike other GNSS receivers on the market, EVA is a standalone GNSS receiver which provides a position without the need for host integration or extra RF components. It is optimized for keeping eBOM and system costs to an absolute minimum.
“The EVA-7M brings embedded satellite positioning to the next level of portability. The module has been developed with ease-of-manufacturing as a high priority. Its QFN-like footprint with connections along four sides and high-level of component integration makes it a perfect solution for medium and high volume production runs. This ensures high first-pass production yield, crucial criteria especially for cost-sensitive, high-volume industrial and consumer applications,” said Thomas Nigg, VP Product Marketing at u-blox.
A UART, USB, SPI and I2C 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.
The module is suitable for consumer, industrial and after-market vehicle applications. First samples will be available in Q1 2014.
