ZOE-M8B is u-blox’s ultra small, highly integrated GNSS SiP (System in Package), measuring just 4.5 x 4.5 x 1.0 mm.

Making use of the Super-Efficient (Super-E) mode, ZOE-M8B offers an ideal balance between miniature size, low power consumption and good GNSS performance. ZOE-M8B uses up to 2.5 times less power than its pin-to-pin compatible counterpart, ZOE-M8G (running in 1 Hz full power mode), while still maintaining good positioning and speed accuracy. An average power consumption over a typical 30-minute track will be as low as 25 mW. This is true even when using an industrial antenna design with moderate-to-low signal levels. Super-E has a default performance setting for the best balance between power vs. performance. It also has a power save setting for additional power savings with potential compromise on performance.

The TCXO-based ZOE-M8B integrates a front-end SAW filter and an additional front-end LNA for increased jamming immunity and easier antenna integration. A passive antenna can be used to provide a highly integrated system solution with minimal eBOM.

Incorporating ZOE-M8B into customer designs is simple and straightforward thanks to the fully integrated design, single 1.8 V voltage supply, simple interface, and sophisticated interference suppression, which ensures maximum performance even in GNSS-hostile environments. In addition, the ZOE-M8B provides an SQI interface for optional external flash, continuous data logging, and improved A-GNSS performance.

ZOE-M8B is based on the high performance u-blox M8 concurrent GNSS engine, which supports GPS / GLONASS / BeiDou / GalileoC, including message integrity protection, anti-jamming, and anti-spoofing. All of these features together provide reliable positioning in difficult environmental conditions, as well as in security attack scenarios.

The ZOE-M8B SiP can be easily integrated in manufacturing thanks to the advanced S-LGA (Soldered Land Grid Array) packaging technology, which enables easier and more reliable soldering processes compared to a normal LGA (Land Grid Array) package. It is fully tested and qualified according to the JESD47 / ISO 16750 standard.
