Product description
The u-blox CAM-M8 series antenna modules are built on the
exceptional performance of the u-blox M8 GNSS engine. The
CAM-M8 modules utilize concurrent reception of up to three
GNSS systems (GPS/Galileo together with either BeiDou or
in an ultra compact form factor.
Incorporating the CAM-M8 series modules into customer de-
signs is simple and straightforward, thanks to the embedded
GNSS antenna, small footprint of 9.6 x 14 x 1.95 mm, and so-
phisticated interference suppression that ensures maximum
performance even in GNSS-hostile environments. The low
power consumption and thin design allow end devices to be
slimmer and smaller. The CAM-M8 modules also support mes-
Despite their miniature size, the chip antennas in the
CAM-M8 series modules perform extremely well against
traditional patch antennas. Optimal performance is achieved
by following design instructions available in the Hardware
Integration Manual as the customer PCB is part of the anten-
na solution. The omnidirectional radiation pattern increases
modules can be connected to an external GNSS antenna. The
SMD design keeps manufacturing costs to a minimum and
the small mass ensures high reliability.
The CAM-M8 modules target industrial and consumer appli-
cations that require concurrent GPS/Galileo and GLONASS
or GPS/Galileo and BeiDou reception. The CAM-M8C is op-
timized for cost-sensitive applications and has the lowest
power consumption, while the CAM-M8Q provides best per-
formance. The CAM-M8 modules are form-factor compatible
with the UC530 and UC530M modules, allowing the upgrade
ISO16750 standard: “Road vehicles – Environmental condi-
tions and testing for electrical and electronic equipment”.
