Overview
The EVA-M8M standalone concurrent GNSS modules feature the exceptional performance of the u-blox M8
positioning engine (GPS/QZSS, GLONASS, and BeiDou signals). The EVA-M8M series delivers high sensitivity and
minimal acquisition times in the ultra compact EVA form factor.
The EVA-M8M series is an ideal solution for cost and space-sensitive applications. It is easy to design-in, only
requiring an external GNSS antenna in most applications. The layout of the EVA-M8M modules is especially
designed to ease the customer’s design and limit near field interferences since RF and digital domains are kept
separated.
The EVA-M8M series uses a crystal oscillator for lower system costs. Like other u-blox GNSS modules, the
EVA-M8M uses components selected for functioning reliably in the field over the full operating temperature
range.
With dual-frequency RF front-end, the u-blox M8 concurrent GNSS engine is able to intelligently use the highest
amount of visible satellites from two GNSS (GPS, GLONASS and BeiDou) systems for reliable positioning. The
EVA-M8M series comes in two variants. The EVA-M8M-0 defaults to GPS/QZSS/GLONASS and fits global
applications, whereas EVA-M8M-1 defaults to GPS/QZSS/BeiDou making it the ideal module for China. The right
satellite constellations can be selected without touching software, and therefore reducing the design and testing
effort.
The EVA-M8M modules can be easily integrated in manufacturing, thanks to the QFN-like package and low
moisture sensitivity level. The modules are available in 500 pcs/reel, ideal for small production batches. The
EVA-M8M modules combine a high level of integration capability with flexible connectivity options in a miniature
package. This makes them perfectly suited for industrial and mass-market end products with strict size and cost
requirements. The DDC (I2C compliant) interface provides connectivity and enables synergies with u-blox cellular
modules.
The EVA-M8M modules are manufactured in ISO/TS 16949 certified sites and qualified as stipulated in the
JESD47 standard.
For applications needing firmware update capability or data logging, the EVA-M8M series must be
connected to an external SQI Flash memory. For more information about product features, see the
