Product details
Overview
X-NUCLEO-LIV4A1 from STMicroelectronics is an Arduino UNO R3– and STM32 Nucleo–compatible GNSS expansion board based on the Teseo-LIV4F dual-band module, delivering simultaneous GPS/Galileo/Glonass/BeiDou/QZSS positioning with -162 dBm tracking sensitivity, 3.3–5 V supply operation, and integrated cross-dipole multiband antenna.
For engineers reviewing the X-NUCLEO-LIV4A1 datasheet, X-NUCLEO-LIV4A1 pinout, X-NUCLEO-LIV4A1 application, or X-NUCLEO-LIV4A1 equivalent, this board enables rapid prototyping of location-aware embedded systems using UART/I²C interfaces, PPS timing output, wakeup-triggered low-power tracking, and assisted GNSS via real-time server or autonomous AGNSS.
Technical Context
The board integrates the Teseo-LIV4F module - a compact 9.7 × 10.1 mm GNSS engine featuring an on-board TCXO for temperature-stable timing and a dedicated RTC oscillator to reduce time-to-first-fix (TTFF). It runs X-CUBE-GNSS1 firmware internally, performing full GNSS signal acquisition, tracking, navigation, and NMEA data output without external memory.
Hardware interfaces include UART (PA9/PA10 default on Nucleo), I²C (SDA/SCL), configurable digital I/O, EXTINT wakeup input, and SYS_PPS pulse-per-second output. The SMA female antenna connector supports external antennas, while the included active cross-dipole antenna covers GPS L1/E1 + Galileo E1 + BeiDou B1I + Glonass G1 + QZSS L1 bands.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| GNSS Constellations | Simultaneous GPS, Galileo, Glonass, BeiDou, QZSS - enables global coverage and improved position availability in urban canyons. |
| Tracking Sensitivity | -162 dBm - allows reliable satellite signal lock under weak-signal conditions such as indoors or dense foliage. |
| Supply Voltage Range | 3.3 V to 5 V - compatible with both STM32 Nucleo 3.3 V logic and Arduino UNO 5 V domains via level-shifting circuitry. |
| Operating Temperature | +10 °C to +50 °C - validated for indoor and controlled-environment industrial deployment, not extended automotive or outdoor extremes. |
| Antenna Interface | SMA female + integrated active cross-dipole multiband antenna - eliminates need for separate RF front-end design or antenna matching. |
| Communication Interfaces | UART (TTL), I²C, and configurable GPIO - supports host MCU integration via standard serial protocols without custom transceivers. |
| Timing Output | SYS_PPS (pulse-per-second) - provides traceable 1 Hz timing reference synchronized to GNSS time for timestamping or clock discipline. |

FAQ
Does X-NUCLEO-LIV4A1 require external flash or RAM to operate?
No. The onboard Teseo-LIV4F module executes X-CUBE-GNSS1 firmware entirely within its internal memory, handling GNSS acquisition, tracking, navigation, and NMEA output without external storage or processing resources.
Can X-NUCLEO-LIV4A1 be used with non-ST MCUs?
Yes. Its UART and I²C interfaces are protocol-standard and voltage-tolerant (3.3 V logic), enabling direct connection to any MCU supporting those buses - including ESP32, nRF52, or PIC32 - provided level-shifting is applied for 5 V hosts.
What is the role of the CR2032 battery socket on the board?
The CR2032 holder powers the Teseo-LIV4F's backup domain to retain ephemeris data and RTC state during main power loss, reducing TTFF from cold to warm start - critical for battery-operated trackers needing fast reacquisition.
Is assisted GNSS (AGNSS) functionality enabled out-of-the-box?
Yes. The board supports both autonomous AGNSS (storing orbital data locally) and real-time server-based AGNSS via UART commands, allowing immediate position fix without waiting for full ephemeris download from satellites.
