Overview
The EVA-8M / EVA-M8 series GNSS modules feature the excellent performance of the u-blox 8 / u-
blox M8 positioning engine. The EVA-8M / EVA-M8 series delivers high sensitivity and minimal
acquisition times in the ultra-compact EVA form factor.
The EVA-8M / EVA-M8 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-8M
/ EVA-M8 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-8M and EVA-M8M series module uses a crystal oscillator for lower system costs, while EVA-
M8Q with TCXO provides best performance. Like other u-blox GNSS modules, the EVA series uses
components selected for functioning reliably in the field over the full operating temperature range.
The EVA-M8M and EVA-M8Q modules include a dual-frequency RF front-end, with which the u-blox
M8 concurrent GNSS engine is able to intelligently use the highest amount of visible satellites from
up to three GNSS (GPS/Galileo, together with GLONASS or 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-8M includes a single-frequency RF front-end, and can receive and track either GPS or
GLONASS signals.
The EVA-8M and EVA-M8 series 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-8M and EVA-M8 series 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-8M and EVA-M8 series modules are qualified as stipulated in the JESD47 standard.

For applications needing data logging capability, storing configurations and hold AssistNow data,
the EVA-8M / EVA-M8 series GNSS modules must be connected to an external SQI Flash memory.
Firmware update form SQI Flash memory is only supported with EVA-M8M and EVA-M8Q series
GNSS modules. For more information about product features, see the
EVA-M8 Data Sheet [1] and
the
EVA-8M Data Sheet [2]
