X-NUCLEO-GNSS1A1

X-NUCLEO-GNSS1A1 GNSS Expansion Board

STMicroelectronics X-NUCLEO-GNSS1A1 GNSS Expansion Board is based on the Teseo-LIV3F tiny GNSS module. The board is an affordable, easy-to-use global navigation satellite system (GNSS) module. The  X-NUCLEO-GNSS1A1 embeds a TeseoIII single die standalone positioning receiver IC, usable in different configurations in STM32 Nucleo projects. The Teseo-LIV3F is a compact (9.7mm x 10.1mm) module with 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 complete GNSS firmware (X-CUBE-GNSS1) to perform all GNSS operations, including acquisition, tracking, navigation, and data output without external memory support. TheSTMicroelectronics X-NUCLEO-GNSS1A1 GNSS 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.
