u-blox MAX-M8W

Part no.: MAX-M8W-0
Manufacturer: u-blox

Availability: In Stock

The MAX-M8 series of standalone concurrent GNSS modules is built on the exceptional performance of the u-blox M8 engine in the industry proven MAX form factor. With dual-frequency RF front-end, the u-blox M8 concurrent GNSS engine is able to intelligently use the highest amount of visible satellites from two GNSS (GPS, GLONASS and BeiDou) systems for more reliable positioning. The MAX-M8 series is ideal for performance driven applications.

The MAX-M8 series provides high sensitivity and minimal acquisition times while maintaining low system power. The MAX‑M8C is optimized for cost sensitive applications and has the lowest power consumption, the MAX-M8Q provides best performance for passive and active antennas designs, 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. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments.

The MAX‑M8 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 also 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”.
