Product description

EVA-M8E

The EVA-M8E SiP introduces u-blox’s Untethered Dead Reckoning (UDR) technology in the ultra-compact EVA form-factor.
Measuring merely 7 x 7 mm, the EVA-M8E offers the designer
flexibility in the selection and placement of peripheral components. The EVA-M8E only requires flash memory, an inertial
sensor, and an optional real-time clock (RTC) crystal. The EVAM8E’s sensor may be installed in any stable position within thevehicle without configuration.
UDR provides the benefits of Dead Reckoning (DR) without
requiring speed information from the vehicle. This significantly reduces the cost of installation for after-market DeadReckoning applications and brings DR performance to applications where previously only GNSS was possible. The strengthof UDR compared with GNSS alone is particularly apparent
under poor signal conditions in urban environments, where it
brings continuous positioning even to devices with antennas
installed within the vehicle. Useful positioning performance isalso available during complete signal loss, for example in parking garages and short tunnels. UDR positioning starts as soon
as power is applied to the SiP, even before the first GNSS fix isavailable. Inertial sensing enables vehicle yaw, pitch, and roll tobe calculated and reported directly.

The intelligent combination of GNSS and sensor measurements enables accurate, real-time positioning at rates up
to 30 Hz, as needed for smooth and responsive interactiveapplications. Native high-rate sensor data can be relayed tothe host for applications such as driving behaviour analysis oraccident reconstruction.

The EVA-M8E includes u-blox’s latest generation GNSS receiver, which adds Galileo to the multi-constellation reception that
already includes GPS, GLONASS, BeiDou and QZSS. The SiP
provides high sensitivity and fast GNSS signal acquisition andtracking. UART, USB, DDC (I2C compliant) and SSI interface
options provide flexible connectivity and enable simple integration with most u-blox cellular modules.
