EVA-M8 Series - Ultra compact standalone concurrent multi-GNSS modules

EVA-M8 is an ideal solution for cost and space sensitive industrial and wearable applications, generally only requiring an external GNSS antenna.

The EVA-M8M and EVA-M8Q GNSS modules feature the superior performance of the u-blox M8 concurrent positioning engine, supporting GPS, Galileo, GLONASS and BeiDou. The EVA-M8 series delivers high sensitivity in the ultra compact EVA form factor of 7.0 x 7.0 x 1.1 mm.

The EVA-M8 series is an ideal solution for cost and space sensitive industrial and wearable applications. It is easy to design-in, only requiring an external GNSS antenna in most applications. The layout of the EVA-M8 modules is especially designed to simplify the customer's design and limit near-field interferences, as RF and digital domains are kept separate. The EVA-M8Q is ideal for designs with small antennas or covert installations, whereas EVA-M8M is the preference when system costs matter most.

With a dual-frequency RF front-end, the EVA-M8 concurrent GNSS modules are able to intelligently use the highest number of visible satellites from three GNSS systems (GPS and Galileo together with GLONASS or BeiDou) for reliable positioning.

The EVA-M8 series modules provide a Serial Quad Interface (SQI) for optional external FLASH, which can be used for future firmware upgrades and improved Assistance GNSS performance. The EVA-M8 series also supports message integrity protection, geofencing and spoofing detection. The migration from previous generations is easy, as the EVA-M8 series is pin-compatible to EVA-8M and EVA-7M modules.

The EVA-M8 series combines a high level of integration capability with flexible connectivity options in a miniature package. It can be easily integrated in manufacturing, thanks to the QFN-like package. The modules are available in 500 pcs/ reel, which is ideal for small production batches. The DDC (I 2 C compliant) interface provides connectivity and enables synergies with most u-blox cellular modules.

The EVA-M8M and EVA-M8Q modules are fully tested and qualified according to the JESD47 standard.
