The NEO-M8M series of standalone concurrent GNSS modules is built on the exceptional performance of the u-blox M8 GNSS (GPS, GLONASS, BeiDou, QZSS and SBAS) engine in the industry proven NEO form factor. The NEO-M8Q/M series provides high sensitivity and minimal acquisition times while maintaining low system power. The NEO‑M8M is optimized for cost sensitive applications, while NEO-M8Q provides best performance and easier RF integration.
The NEO form factor allows easy migration from previous NEO generations. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments. The NEO-M8Q/M combines a high level of robustness and integration capability with flexible connectivity options. Thismakes NEO-M8Q/M perfectly suited to industrial and automotive applications.
The DDC (I 2 C compliant) interface provides connectivity and enables synergies with most u‑blox cellular modules. For RF optimization the NEO-M8Q features an additional front-end LNA for easier antenna integration and a front-end SAW filter for increased jamming immunity.
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”.
The HMC5983 includes state-of-the-art, high-resolution HMC118X series magnetoresistive sensors plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass heading accuracy. The I²C or SPI serial bus allows for easy interface. The HMC5983 is a 3.0 x 3.0 x 0.9 mm surface mount 16-pin leadless chip carrier (LCC).
The HMC5983 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over other magnetic sensor technologies. Honeywell’s anisotropic directional sensors excel in linearity, low hysteresis, null output and scale factor stability over temperature, and very low cross-axis sensitivity. These sensors’ solid-state construction is designed to measure both the direction and the magnitude of magnetic fields, from milli-gauss to 8 gauss. Honeywell’s Magnetic Sensors are among the most sensitive and reliable low-field sensors in the industry.
