1.1 Board overview
The
X-NUCLEO-GNSS2A1 expansion board for STM32 Nucleo is a GNSS multiconstellation receiver with dead-
reckoning that covers a wide range of applications where geo-location is required.
The key features are:
• Operating supply voltage: 3.3 V
• Ambient temperature: -40/+85°C
• Sensitivity: -163 dBm (tracking mode)
• Interfaces:
– a UART port
– an I²C port
– configurable digital I/O time pulse
– EXTINT input for wake-up
• NMEA protocol
• Assisted GNSS:
– autonomous AGNSS
– real-time, server-based
• Simultaneous multiconstellation:
– GPS
– Galileo
– Glonass
– BeiDou
– QZSS
• Compatible with
STM32 Nucleo development boards
• Compatible with the Arduino UNO R3 connector
•
Teseo-VIC3DA dead-reckoning automotive firmware
• Provision of FWD and WHEELTICK signals
• Automotive GNSS and 6-axis inertial sensor
• LNA and SAW filters on the RF path
• SMA female antenna connector
• RoHS and WEEE compliant
