X-STM32MP-GNSS2 GNSS MPU Expansion Board

STMicroelectronics' X-STM32MP-GNSS2 is an STM32 MPU expansion board with a Teseo-LIV4F module for low-power multi-constellation GNSS positioning using various sensors for data accuracy. The X-STM32MP-GNSS2 interfaces with the STM32MP microprocessor via 40-pin GPIO connector pins using I²C, UART, and GPIO connections for various components. It is compatible with both STM32MP157F-DK2 and Raspberry Pi GPIO connector layouts.

Teseo-LIV4F is a standalone, low-power, global navigation satellite system (GNSS) module. It embeds the Teseo IV positioning receiver IC, working simultaneously on multiple constellations (GPS, Galileo, Glonass, BeiDou, QZSS, and IRNSS). The ISM330DHCX iNEMO inertial module has a full-scale acceleration range of ±2 g, ±4 g, ±8 g, and ±16 g and a wide angular rate range of ±125 dps, ±250 dps, ±500 dps, ±1000 dps, ±2000 dps, and ±4000 dps.

The ILPS22QS with embedded Qvar technology functions as a digital output barometer, supporting dual full-scale up to 4060 hPa. The IIS2MDC is a high-accuracy, ultralow power, 3-axis digital magnetometer with a dynamic range of up to ±50 gauss.
