X-NUCLEO-GNSS1A1 Hardware 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 Teseo III 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.
