The Neo 6M GPS receiver
The card on which the Neo 6M GPS receiver is mounted has 4 connection pins (starting from the left):

As you can see from the pin names, the GPS receiver is controlled/read out through a
UART. Default baud rate is 9600 baud. The pins on the ESP32 correspond to UART2 of the ESP32 chip.
