Module GNSS DIP Switch Explanation Document

1. Overview

To avoid pin conflicts when Module GNSS is stacked with the main unit, the module uses a DIP switch to flexibly switch the connection of key pins. Users can adjust the corresponding pin configuration based on the host they are using (such as Core/Basic, Core2, or CoreS3) to ensure stable system operation.

2. DIP Switch Position and Pin Mapping

2.1 DIP Switch Position

The DIP switch is located at the specified position on the module, as shown in the diagram below:

2.2 Pin Mapping Table

The pin mapping options for different hosts are as follows:

Note:

• TXD, RXD, PPS can be selected through the DIP switch to choose the specific pin to connect. For example, on Core (Basic) host:
  • PPS: Choose from G34, G35, or G0 (one of the three)
  • TXD: Choose from G0, G12, G15, or G17 (one of the four)
  • RXD: Choose from G35, G34, G13, or G16 (one of the four)

3. DIP Switch Switching Operation

Please follow the steps below to adjust the DIP switch configuration:

1. Power Off
   Before adjusting the DIP switch, make sure the module is completely powered off to avoid hardware damage.

2. Set the DIP Switch
   Select the corresponding pin mapping according to the host you are using.

   

3. Rewire and Power On
   After setting the DIP switch, reconnect the module and power it on for subsequent use.
