The industry’s smallest standalone GNSS module

The smallest standalone GNSS positioning module on the market, the EVA-7M, has today been introduced by u-blox. Available in a 7mm x 7mm x 1.1mm LGA package, the new GNSS module supports US GPS, Russian GLONASS, Japanese QZSS, plus all SBAS augmentation systems and is designed for cost and space sensitive applications.

The EVA-7M module comprises all necessary components, including crystal and passives. For instant global positioning capability, just add an antenna.

Achieving -160 dBm sensitivity when tracking GPS satellites (-158 dBm with GLONASS satellites), the new GNSS positioning module features a fast acquisition time and is based on u-blox’ advanced GNSS technology u‑blox 7. An innovative high-efficiency power converter means that the EVA-7M offers the lowest power of any u-blox 7 module, 16.5 mA at 3 V.

Thomas Nigg, VP Product Marketing at u-blox, commented: “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."

Keeping RF and digital domains separate, and with the LGA pads configured in single rows, the EVA-7M eases implementation in end-products. Optimised for keeping eBOM and system costs to an absolute minimum, EVA is a standalone GNSS receiver which provides a position without the need for host integration or extra RF components.

Suitable for consumer, industrial and after-market vehicle applications, the EVA-7M provides flexible connections to a host processor with UART, USB, SPI and I2C interfaces. The 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. Samples will first be available in Q1 2014.
