Bringing concurrent multi-GNSS performance into the ultra-compact EVA footprint, u-blox's EVA-M8M stand-alone positioning module is hailed as the world’s smallest commercially available GNSS module. Designed for cost- and space-sensitive applications, the integrated 7x7x1.1mm LGA module comprises all necessary components, including crystal and passives.

The EVA-M8M requires only an external antenna to provide an accurate position without the need for host integration. The module is also compatible with the popular EVA-7M GPS module, to allow easy upgrading of existing designs at minimal cost.

Supporting US GPS, Russian GLONASS, Chinese BeiDou, Japanese QZSS, and SBAS augmentation systems, the module achieves -164dBm tracking sensitivity, fast acquisition time and low power consumption. Able to track any two GNSS systems simultaneously, the EVA-M8M can output a GNSS position up to 18Hz.

A UART, USB, SPI and I2C interface provide flexible connections to a host processor, whilst the EVA-M8M can also communicate directly with u‑blox’ SARA 2G, LISA 3G and TOBY 4G cellular modules to support advanced tracking and location-aware products.

“The EVA-M8M sets a new industry benchmark for compact, stand-alone global positioning performance. The module has been designed for the absolute lowest eBOM costs and ease-of-manufacturing. It is a perfect solution for cost-sensitive industrial and wearable devices,” concluded Thomas Nigg, Vice President, Product Strategy, u-blox.

For existing designs using a NEO module, the C88-M8M adaptor board can be used for easy evaluation of the EVA-M8M in existing NEO-xM designs.
