STMicroelectronics EVB-LIV3F

Overview

EVB-LIV3F from STMicroelectronics is a dedicated evaluation board for the Teseo-LIV3F multiconstellation GNSS module, integrating ARM-based processing, UART/I²C interfaces, PPS timing output, and onboard USB power/battery charging circuitry. It supports GPS, Galileo, GLONASS, BeiDou, and QZSS, and enables standalone operation via internal battery footprint.

For engineers reviewing the EVB-LIV3F datasheet, EVB-LIV3F pinout, EVB-LIV3F application, or EVB-LIV3F equivalent, this board provides validated hardware access to NMEA over USB-UART, I²C signals via header, SMA antenna interface, VCC/VCC_IO test points, and real-time PPS synchronization - critical for GNSS receiver validation and embedded navigation prototyping.

Technical Context

The EVB-LIV3F implements a complete hardware abstraction layer for the Teseo-LIV3F module, exposing its UART and I²C peripherals through standardized connectors while maintaining direct access to power rails (VCC, VCC_IO) and timing signals (PPS). It includes ON/OFF and Reset pushbuttons for controlled module lifecycle management.

Power delivery is dual-path: 5 V USB input with integrated battery charging circuitry, plus provision for an external Li-ion cell via footprint. The SMA antenna connector ensures RF integrity, and LED indicators provide immediate visual feedback for PPS pulses and power status.

FAQ

Does EVB-LIV3F include the Teseo-LIV3F module?

Yes, the EVB-LIV3F evaluation board ships with the Teseo-LIV3F GNSS module pre-mounted. The module integrates an ARM processor, flash memory, and GNSS baseband engine - no separate module purchase is required to begin evaluation.

What software tools are required to communicate with the board?

The ST Teseo Suite Light PC tool is required for configuration, data logging, and performance analysis. It is freely downloadable from st.com. A Silicon Labs CP210x USB-to-UART bridge driver is also needed for virtual COM port communication.

Can EVB-LIV3F operate without a PC connection?

Yes - it supports standalone operation using an external Li-ion battery soldered to the onboard footprint. USB power is optional; the integrated charger maintains battery health during connected use, enabling field testing without host dependency.

Is an antenna included in the kit?

Yes, the standard kit includes a passive GNSS patch antenna with SMA male connector, optimized for L1-band (1575.42 MHz) reception and calibrated for use with the EVB-LIV3F's 50 Ω SMA female port.
