STMicroelectronics X-NUCLEO-GNSS1A1 GNSS Expansion Board | Teseo-LIV3F Positioning Shield | For Global Navigation & Asset Tracking
Description
SPIDER Automation STMicroelectronics X-NUCLEO-GNSS1A1 GNSS Expansion Board provides a cost-effective and easy-to-use global navigation satellite system (GNSS) solution for STM32 Nucleo development ecosystems. Centered around the powerful Teseo-LIV3F module, this shield embeds a standalone TeseoIII single-die positioning receiver IC capable of high-precision location tracking.
The expansion board operates on a 3.3V to 5V power supply and communicates smoothly via UART and I²C ports. It features flexible configuration options including a digital I²O timepulse and an EXTINT input for device wakeup. Designed with the Arduino UNO R3 connector layout and ST morpho headers, the X-NUCLEO-GNSS1A1 can be mounted directly onto STM32 Nucleo boards or stacked with additional expansion shields for comprehensive IoT prototyping.
