ZOE-M8B - Ultra-compact, super low power u-blox M8 GNSS SiP with Super-E mode

Ultra small multi-GNSS SiP modules for battery powered wearable and portable devices

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 a traditional M8 GNSS module with concurrent GNSS reception 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, using AssistNow Offline data and an industrial antenna design (i.e. moderate-to-low signal levels).

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, antijamming, and anti-spoofing. All of these features together provide reliable positioning in difficult environmental conditions, as well as in security attack scenarios.

ZOE-M8B with Super-E low power mode is an ideal and fully integrated SiP solution for battery powered wearable and portable devices requiring low power and small size with good GNSS performance.
