Conformity and Certification


The MAX‑7 series of standalone GNSS modules is built on the exceptional performance of the u‑blox 7 multi‑GNSS (GPS, GLONASS, QZSS and SBAS) engine. The MAX‑7 series delivers high sensitivity and minimal acquisition times in the ultra compact MAX form factor. The MAX‑7 series provides maximum sensitivity while maintaining low system power. The MAX‑7C is optimized for cost sensitive applications. The MAX‑7Q provides best performance and lowest power, while the MAX‑7W provides best performance and is optimized for active antennas. The industry proven MAX form factor allows easy migration from MAX‑6 modules. Sophisticated RF‑architecture and interference suppression ensure maximum performance even in GNSS‑hostile environments. The MAX‑7 series combines a high level of integration capability with flexible connectivity options in a miniature package. This makes it 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. u‑blox 7 modules use GNSS chips qualified according to AEC‑Q100 and are manufactured in ISO/TS 16949 certified sites. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”. MAX‑7Q complies with green/halogen free standards.
