STMicroelectronics GNSS Expansion Board Based on Teseo-LIV3F Module for STM32 Nucleo X-NUCLEO-GNSS1A1 Evaluation Kit

STMicroelectronics X-NUCLEO-GNSS1A1 is a high-performance GNSS Expansion Board designed for STM32 Nucleo and Arduino UNO R3 compatible development platforms. It features the Teseo-LIV3F GNSS module, enabling reliable satellite positioning and navigation with RF GNSS technology operating up to 26 MHz. The operating supply voltage ranges between 3.3 and 5 volts, suitable for a variety of embedded system configurations.

This evaluation kit supports multiple interfaces including UART and I²C serial communication with additional configurable digital I/O and timepulse signals for precise timing applications. The board offers an EXTINT input to facilitate wakeup from low power states and uses the NMEA protocol for GNSS data output.

Designed with a high sensitivity reaching -162 dBm in indoor tracking mode, the device ensures excellent performance even in challenging RF environments. The RF path includes a low noise amplifier (LNA) and a surface acoustic wave (SAW) filter coupled with an SMA female connector for external antenna connection, improving signal quality and reliability.

The battery holder on board allows power backup for the GNSS module aiding in faster cold start times and reliable position fixes. The ambient operating temperature range of -40 to +85 °C enables deployment in diverse environmental conditions, making it suitable for industrial, laboratory, and prototyping use in navigation, tracking, and location-based services development.

The product is RoHS compliant and manufactured in Italy, promising quality and environmental safety compliance. Its compatibility with popular development boards like STM32 Nucleo and Arduino UNO R3 connectors provides flexibility for developers and engineers working in embedded systems, IoT, and GNSS applications.
