2.1 X-NUCLEO-GNSS2A1 expansion board for STM32 Nucleo
The
X-NUCLEO-GNSS2A1 allows testing the Teseo-VIC3DA GNSS module functionality via the firmware
package contained in the X-CUBE-GNSS1 software.
Important: Program the microcontroller on the
STM32 Nucleo development board.
The
Teseo-VIC3DA module and the STM32 Nucleo development board communicate through the expansion
board connectors (CN5, CN6, CN8, and CN9) as listed in the tables below.
