MAX-8 Series - u-blox 8 GNSS modules

MAX-8 series of u-blox 8 standard precision GNSS modules, offering high sensitivity and minimal acquisition times

The MAX-8 series of standard precision GNSS modules features the reliable performance of the u-blox 8 positioning engine, which receives GPS, GLONASS, QZSS and SBAS signals. The MAX-8 series delivers high sensitivity and minimal acquisition times in the ultra compact MAX form factor.

MAX-8 is an economical series of modules which provide high sensitivity while featuring low power consumption and supporting advanced Power Save Modes. They also provide message integrity protection, geofencing, spoofing detection, and odometer functionalities.

The MAX-8C is optimized for cost sensitive applications with lowest power, while the MAX-8Q provides best performance. The industry proven MAX form factor allows easy migration from MAX-7 and MAX-6 modules by offering backward compatibility. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS hostile environments.

MAX-8 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 most u-blox cellular modules.

Key Features:
  • High sensitivity of -166 dBm for single GNSS reception
  • Cost‑efficient system
  • TCXO‑based variant for fastest time to first fix
  • Low power consumption
  • Superior anti‑spoofing and anti‑jamming
  • Pin‑compatible to MAX‑7
