Introduction

The X-NUCLEO-GNSS2A1 expansion board is based on the Teseo-VIC3DA tiny GNSS module. It represents an affordable,

easy-to-use, global navigation satellite system (GNSS) module, which embeds a TeseoIII single die standalone positioning

receiver IC, usable in different configurations in your STM32 Nucleo project.

The

Teseo-VIC3DA is a compact (16.0 x 12.2 mm) module that provides superior accuracy thanks to the on-board temperature

compensated crystal oscillator (TCXO) and a reduced time-to-first fix (TTFF) with its dedicated real-time clock (RTC) oscillator.

The

Teseo-VIC3DA module runs the GNSS firmware (X-CUBE-GNSS1) to perform all the GNSS operations including

acquisition, tracking, navigation, and data output without any external memory support.

The

X-NUCLEO-GNSS2A1 expansion board is compatible with the Arduino UNO R3 connector and the ST morpho connector. It

can be plugged to an STM32 Nucleo development board and stacked with additional STM32 Nucleo expansion boards.
