New u-blox UBX-M10150-CC GNSS Chip with LEAP Technology for Wearable Devices Offers Ultra-Low Power and High Accuracy
u-blox has introduced the UBX-M10150-CC, an ultra-low power GNSS chip designed for wearable devices like sports and smartwatches. Measuring just 2.39 x 2.39 x 0.55 mm, it is the smallest form factor in its category, enabling sleek and compact designs. It supports multiple GNSS systems, including GPS, BeiDou, Galileo, and QZSS, and offers high positioning accuracy with pioneering LEAP (Low Energy Accurate Positioning) technology, consuming only 10 mW of power.
The chip features multi-path mitigation for better performance in urban environments, modes for activities like running, cycling, and swimming, and firmware upgradeability for adding new capabilities over time. With support for Android and SUPL, it integrates easily into devices. Precise positioning, energy efficiency, and compact size are required for wearable applications.
This chip operates efficiently with a supply voltage range of 1.0 V to 1.8 V, a backup supply of 1.65 V to 3.6 V, and digital I/O voltage options of 1.8 V or 3.3 V. It also supports a wide temperature range from −20 °C to +65 °C for operation and −40 °C to +125 °C for storage.

Previously, u-blox released its X20 all-band GNSS module, which supports Multi-Band signals for high-precision positioning. We have also learned about this GNSS platform for enhanced positioning accuracy in urban environments by u-blox.
The UBX-M10150-CC is compatible with u-blox AssistNow and CloudLocate services and is supported by the u-blox M10 GNSS evaluation kit (EVK-M102). This kit includes a firmware-upgradable chip, a TCXO, and a 14-pin connector for SPI/I2C communication and current measurements. Housed in a compact metal enclosure, it is USB-powered and comes with u-center 2 software for easy configuration, testing, and data analysis via USB or RS232. For more details, refer to the EVK-M102 product page.

At the time of writing, the company has announced that initial samples of the UBX-M10150-CC GNSS receiver chip are now available but has not provided pricing information for the chip or the EVK-M10 evaluation kit.
