Connecting the Arduino GPS shield with the Arduino Ethernet board

To connect the Arduino GPS shield with the Arduino Ethernet board, perform the following steps:

  1. Stack your Arduino GPS shield with the Arduino Ethernet board.
  2. Move the UART/DLINE switch to the DLINE position. This is a two-way switch that can be used to select the UART or DLINE mode to communicate GPS shield with Arduino.
    • UART: This connects the GPS module's serial lines to Arduino hardware serial (D0/RX and D1/TX).
    • DLINE: This connects the GPS module's serial lines to the Arduino software serial (D2 and D3). See the solder marks label next to the UART/DLINE switch.
