MAX-M8 series
Small u-blox M8 GNSS modules
Product description
The MAX-M8 series of concurrent GNSS modules is built on
the exceptional performance of the u-blox M8 engine in the
industry proven MAX form factor.
The MAX-M8 modules utilize concurrent reception of up to
three GNSS systems (GPS/Galileo together with either Bei-
Dou or GLONASS) for more reliable positioning. The MAX-M8
series provides high sensitivity and minimal acquisition
times while maintaining low system power. It also supports
message integrity protection, geofencing, and spoofing
detection.
The MAX-M8C is optimized for cost-sensitive applications
and has the lowest power consumption, the MAX-M8Q pro-
vides best performance for passive and active antennas de-
signs, while the MAX-M8W is optimized for active antennas
with best performance. The industry-proven MAX form factor
allows easy migration from previous MAX generations. Sophis-
ticated RF architecture and interference suppression ensure
maximum performance even in GNSS-hostile environments.
The MAX-M8 series combines a high level of integration
capability with flexible connectivity options in a miniature
package. This makes MAX-M8 perfectly suited for industrial
applications with strict size and cost requirements. The MAX-
M8Q is also halogen free (green) which makes it a perfect
solution for consumer applications. The DDC (I2C compliant)
interface provides connectivity and enables synergies with
most u-blox cellular modules.
u-blox M8 modules use GNSS chips qualified according to
AEC-Q100, are manufactured in ISO/TS 16949 certified
sites, and fully tested on a system level. Qualification tests
are performed as stipulated in the ISO16750 standard: “Road
vehicles – Environmental conditions and testing for electrical
and electronic equipment”.
