The X-NUCLEO-LIV4A1 expansion board is based on the Teseo-LIV4F tiny dual-band GNSS Low power and measurement engine modules.

It represents an affordable, easy-to-use, global navigation satellite system (GNSS) module, embedding TESEO IV single die GNSS receiver IC working simultaneously on multiple constellations GPS/Galileo/ Glonass/BeiDou/QZSS) able to provide positioning (Teseo-LIV4F) in your STM32 Nucleo project.

The Teseo-LIV4F is a compact (9.7 x 10.1 mm) module that provides superior accuracy thanks to the on-board temperature-compensated crystal oscillator (TCXO) and a reduced time-to-first fix (TTFF) with its dedicated real-time clock (RTC) oscillator.

The Teseo-LIV4F module runs the GNSS firmware (X-CUBE-GNSS1) to perform all GNSS operations including acquisition, tracking, navigation, and data output without external memory support.

The X-NUCLEO-LIV4A1 expansion board is compatible with the Arduino® UNO R3 connector and the ST morpho connector, so it can be plugged to the STM32 Nucleo development board and stacked with additional STM32 Nucleo expansion boards
