Swiss-based u‑blox has introduced the EVA‑M8M stand-alone positioning module. The EVA-M8M GNSS module brings concurrent multi-GNSS performance into the ultra-compact EVA footprint.

Designed for cost- and space-sensitive applications, the highly integrated 7 x 7 x 1.1 mm LGA module comprises all necessary components, including crystal and passives. EVA-M8M only requires an external antenna to provide an accurate position without the need for host integration. Components have been selected for reliable operation in the field over the full operating temperature range. The module is also compatible with the EVA-7M GPS module, allowing for easy upgrading of existing designs at minimal cost, u-blox said.

The module supports GPS, GLONASS, BeiDou, QZSS, and SBAS augmentation systems. Based on u‑blox M8 performance, the module achieves -164 dBm tracking sensitivity, fast acquisition time and low power consumption. EVA-M8M can track any two GNSS systems simultaneously and output a GNSS position up to 18 Hz.

“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,” said Thomas Nigg, vice president of product strategy at u-blox.

A UART, USB, SPI and I2C interface provide flexible connections to a host processor. 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.

Detailed information about the EVA-M8M can be found on the u-blox website. Samples are available now. 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.
