STMicroelectronics X-STM32MP-GNSS1 Expansion Board

STMicroelectronics X-STM32MP-GNSS1 Expansion Board features the Teseo-LIV3FL module for low-power, multi-constellation GNSS positioning. The STMicroelectronics X-STM32MP-GNSS1 interfaces with the STM32MP microprocessor via a 40-pin GPIO connector, supporting I²C, UART, and GPIO connections for various components. Compatible with STM32MP157F-DK2 and Raspberry Pi GPIO layouts, the board incorporates the Teseo-LIV3FL GNSS module for global navigation satellite system (GNSS) positioning across multiple constellations (GPS / Galileo / Glonass / BeiDou / QZSS). Additional components include the iNEMO ISM330DHCX inertial module with adjustable acceleration and angular rate ranges, the QVAR Embedded ILPS22QS digital barometer, and the IIS2MDC 3-axis digital magnetic sensor with high accuracy and ultra-low power consumption.
