Product details

Overview

X-NUCLEO-GNSS2A1 from STMicroelectronics is an automotive-grade GNSS expansion board based on the Teseo-VIC3DA module, integrating a dead-reckoning GNSS receiver and 6-axis inertial sensor. It operates at 3.3 V, supports -40/+85°C ambient temperature, delivers -163 dBm tracking sensitivity, and enables multiconstellation positioning (GPS/Galileo/GLONASS/BeiDou/QZSS) for high-accuracy vehicle navigation systems.

For engineers reviewing the X-NUCLEO-GNSS2A1 datasheet, X-NUCLEO-GNSS2A1 pinout, X-NUCLEO-GNSS2A1 application, or X-NUCLEO-GNSS2A1 equivalent, key selection considerations include UART/I²C interface compatibility with STM32 Nucleo boards, real-time assisted GNSS (AGNSS), TCXO-stabilized timing, FWD/WHEELTICK signal provision, and Arduino UNO R3 connector support.

Technical Context

The board implements a tightly coupled GNSS/inertial dead-reckoning architecture using the Teseo-VIC3DA module, which embeds a standalone TeseoIII GNSS receiver IC with integrated RTC oscillator and temperature-compensated crystal oscillator (TCXO) to reduce time-to-first-fix. Firmware X-CUBE-GNSS1 runs entirely on-device without external memory.

It provides dual interface paths: UART (TX/RX) and I²C (SCL/SDA), plus configurable digital I/O including SYS_PPS (1PPS time pulse), SYS_WAKEUP (EXTINT), SYS_IRQ (interrupt), SYS_FWD (forward motion trigger), and SYS_WHEELTICK (wheel rotation counter input), all mapped to STM32 Nucleo morpho and Arduino R3 headers.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	3.3 V nominal - powers GNSS module, IMU, and level-shifting circuitry directly from STM32 Nucleo IO rail.
Operating Temperature	-40 °C to +85 °C - qualified for under-hood and dashboard automotive environments.
Tracking Sensitivity	-163 dBm - enables reliable position lock in urban canyons and partial indoor conditions.
GNSS Constellations	GPS, Galileo, GLONASS, BeiDou, QZSS - simultaneous multiconstellation acquisition improves accuracy and availability.
Dead-Reckoning Support	Teseo-VIC3DA firmware with FWD/WHEELTICK inputs - maintains position during GNSS outages using vehicle motion cues.
Antenna Interface	SMA female connector with integrated LNA and SAW filters - ensures clean RF path and noise immunity.
Interface Standards	UART (3.3 V logic), I²C (standard mode), and configurable GPIO - simplifies integration with STM32 HAL and CubeMX.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, specializing in microcontrollers, sensors, power management, and automotive-grade ICs.

This board belongs to ST's X-NUCLEO ecosystem of STM32 Nucleo-compatible expansion boards, designed to accelerate development of intelligent, sensor-fused, and connectivity-enabled embedded applications.

FAQ

Does X-NUCLEO-GNSS2A1 require external firmware loading?

No. The Teseo-VIC3DA module runs pre-installed X-CUBE-GNSS1 firmware that handles all GNSS operations - acquisition, tracking, navigation, and NMEA output - without external memory or host CPU intervention. Firmware updates are performed via UART using ST's dedicated tools.

What antenna types are supported?

The board features an SMA female connector compatible with active GNSS antennas (e.g., Taoglas CGGBP.18.4.A.02 included in kit) delivering +3.3 V bias. Passive antennas are not supported due to lack of built-in LNA power control; only active antennas with 3.3 V VCC_RF compliance should be used.

Can it operate independently without an STM32 Nucleo board?

No. X-NUCLEO-GNSS2A1 is an expansion board requiring a host STM32 Nucleo development board (e.g., NUCLEO-F401RE, NUCLEO-L476RG) for power, MCU processing, and interface routing. It has no onboard microcontroller or standalone power regulation beyond battery-backed RTC support.

Is the 6-axis IMU accessible via standard interfaces?

Yes. The integrated 6-axis inertial sensor (LSM6DSOX or equivalent) communicates exclusively over the same I²C bus as the GNSS module (shared SCL/SDA lines), using separate slave addresses. ST-provided drivers in X-CUBE-GNSS1 abstract both sensor and GNSS data into unified dead-reckoning outputs.
