X-NUCLEO-GNSS1A1

X-NUCLEO-GNSS1A1 is a GNSS expansion board based on Teseo-LIV3F module for STM32 Nucleo. It represents an affordable, easy-to-use, global navigation satellite system (GNSS) module, embedding a TeseoIII single die standalone positioning receiver IC, usable in different configurations in your STM32 Nucleo project. The Teseo-LIV3F is a compact (9.7x10.1mm) module that provides superior accuracy thanks to the on-board 26MHz temperature compensated crystal oscillator (TCXO) and a reduced time-to-first fix (TTFF) with its dedicated 32KHz real-time clock (RTC) oscillator. The Teseo-LIV3F 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-GNSS1A1 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.
