STMicroelectronics X-NUCLEO-LIV4A1 GNSS Expansion Board

STMicroelectronics X-NUCLEO-LIV4A1 GNSS Expansion Board is based on the Teseo-LIV4F tiny dual-band GNSS low power and measurement engine modules. The affordable, easy-to-use, global navigation satellite system (GNSS) module, embedding TESEO IV single die GNSS receiver IC, works simultaneously on multiple constellations GPS / Galileo / Glonass / BeiDou / QZSS) to provide positioning (Teseo-LIV4F) for user's STM32 Nucleo projects. The compact (9.7mm x 10.1mm) Teseo-LIV4F delivers superior accuracy thanks to an onboard temperature-compensated crystal oscillator (TCXO) and a reduced time-to-first fix (TTFF) with a 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 STMicroelectronics X-NUCLEO-LIV4A1 expansion board is compatible with Arduino® UNO R3 and ST morpho connectors. It can be plugged into an STM32 Nucleo development board and stacked with additional STM32 Nucleo expansion boards.
