Part no.: EVA-M8M-0
Manufacturer: u-blox

Availability: In Stock

The EVA-M8M GNSS modules feature the exceptional performance of the u-blox M8 positioning engine (GPS, GLONASS, BeiDou, QZSS and SBAS). The EVA-M8M series modules 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 spacesensitive applications. It is easy to design-in, only requiring an external GNSS antenna in most applications. The layout of the EVA‑M8M 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 series 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 series can be easily integrated in manufacturing, thanks to the QFN-like package. The modules are available in 500 pcs/reel, ideal for small production batches. The EVAM8M modules combine a high level of integration capability with flexible connectivity options in a miniature package. This makes the EVA-M8M modules perfectly suited for size- and cost-sensitive industrial and wearable devices. 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.
