Product details
Overview
EVB-LIV3FL from STMicroelectronics is a standalone evaluation board for the Teseo-LIV3FL low-power GNSS module, integrating an ARM microprocessor with embedded flash, UART and I²C interfaces, supporting GPS/Galileo/GLONASS/BeiDou/QZSS constellations, dead-reckoning, PPS output, and dual power via USB or battery.
For engineers reviewing the EVB-LIV3FL datasheet, EVB-LIV3FL pinout, EVB-LIV3FL application, or EVB-LIV3FL equivalent, this board enables rapid validation of multiconstellation GNSS positioning, timing accuracy under signal-challenged conditions, battery-powered field deployment, and NMEA/PPS interface integration in industrial tracking and navigation prototypes.
Technical Context
The EVB-LIV3FL implements a complete hardware reference design for the Teseo-LIV3FL module, featuring SMA antenna interface, on-board USB-to-UART bridge for NMEA streaming, dedicated I²C signal connector, VCC/VBAT monitoring points, and discrete ON/OFF and reset controls - all configured for immediate out-of-box operation without external peripherals.
It supports real-time configuration and performance analysis using the ST Teseo Suite PC tool, with firmware updates delivered over USB, and provides observable PPS timing pulses synchronized to GNSS time for precision timestamping validation in embedded navigation systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| GNSS Support | GPS, Galileo, GLONASS, BeiDou, QZSS - enables global positioning coverage with multi-constellation redundancy |
| Dead-Reckoning | Integrated inertial aiding - maintains position accuracy during GNSS signal outages (e.g., tunnels, urban canyons) |
| Power Input | USB 5V or rechargeable battery - supports portable, field-deployable operation without external power supplies |
| Interface Outputs | NMEA over UART (via USB), I²C signals via connector, PPS pulse - delivers standardized navigation data and precise 1PPS timing |
| On-Board Controls | Dedicated ON/OFF and reset buttons - allow full power cycling and module recovery without host intervention |
| Antenna Interface | SMA female connector - enables use of high-gain active GNSS antennas for improved sensitivity and acquisition speed |

FAQ
Does EVB-LIV3FL require external firmware programming before first use?
No. The board ships with pre-flashed Teseo-LIV3FL firmware and is fully operational upon USB connection. The ST Teseo Suite PC tool allows real-time configuration, logging, and firmware updates without additional programmers or debug probes.
Can the EVB-LIV3FL operate solely on battery power without USB connected?
Yes. It supports standalone operation using a rechargeable Li-ion/Li-polymer battery connected via the onboard battery terminals. USB serves both as power source and communication interface, but battery-only mode is fully functional for field testing.
What is the purpose of the PPS output on the EVB-LIV3FL?
The PPS (Pulse Per Second) output provides a precise, GNSS-synchronized timing signal with sub-microsecond jitter, used for time-stamping sensor data, synchronizing distributed nodes, or calibrating system clocks in navigation and timing-critical applications.
Is the I²C interface accessible directly on the board, or only through the signal connector?
The I²C interface (SDA/SCL) is exposed exclusively via the dedicated signal connector - not on-board test points or headers - enabling clean integration with host microcontrollers while preserving signal integrity and avoiding routing conflicts on the evaluation board.
