u-blox announced the latest member of its ZOE M8 series of ultra-small GNSS SiPs. The ZOE M8B is claimed to be the industry’s most power efficient GNSS System in Package (SiP) available for small battery-powered consumer devices. It combines superior performance with ultra-low power to deliver an optimised solution for portable and wearable devices targeting the fitness, health monitoring and personal tracker markets.
The device consumes 25 mW on average in most environments (including urban), and as little as 12 mW during instantaneous tracking. This is a threefold improvement in power efficiency when compared with other variants in the ZOE M8 series. This is thanks to u-blox’s proprietary Super E mode of operation, which automatically adjusts the power consumed by the system components, based on the external conditions.
The footprint of a design with a chip and individual external components is about 50% larger than the PCB footprint of the ZOE M8B. Measuring just 4,5 x 4,5 x 1,0 mm, the ZOE M8B integrates a GNSS receiver, TCXO, SAW and LNA in a single package, making it easy to add accurate location and positioning functionality to almost any device.
The ZOE M8B is the latest addition to the ZOE M8 GNSS module family, which consists of the ZOE M8G for 1,8 V powered devices and the ZOE M8Q for 3,0 V devices, both focusing on maximum accuracy.
