GNSS expansion
board based on
X-NUCLEO-
Teseo-LIV3F
GNSS1A1
module for
STM32 Nucleo
Tiny GNSS
module
Teseo-LIV3F
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 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.
