Description
The X-NUCLEO-GNSS1A1 expansion board is
based on the Teseo-LIV3F tiny GNSS module.
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 (9.7x10.1 mm)
module that provides superior accuracy thanks to
the on-board 26 MHz temperature compensated
crystal oscillator (TCXO) and a reduced time-to-
first fix (TTFF) with its dedicated 32 KHz real-time
clock (RTC) oscillator.
The Teseo-LIV3F module runs complete 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.
