Module LoRa868 v1.2 DIP Switch Instruction Manual

1. Function Overview

To avoid issues with pin conflicts when Module LoRa868 v1.2 is stacked with the host, the module employs DIP switches to flexibly switch the connections of key pins. Users can adjust the corresponding pin configuration based on the host used (such as Core/Basics, Core2, or CoreS3) to ensure stable system operation.

2. DIP Switch Location and Pinmap

2.1 DIP Switch Location

The DIP switches are located in a designated area of the module, as shown in the figure below:

2.2 Pin Mapping Table

For different hosts, the selectable mappings of key pins are as follows:

Note:

• NSS, BUSY, RST, IRQ can be configured via DIP switches to select the specific connection pins. For example, on the Core (Basic) host:
  • NSS: Choose one among G15, G12, G5, or G0 (4 options)
  • BUSY: Choose either G36 or G2 (2 options)
  • RST: Choose either G25 or G13 (2 options)
  • IRQ: Choose one among G35, G34, or G26 (3 options)

3. DIP Switch Configuration Operation

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

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

2. Configure the DIP Switches
   Select the corresponding pin mapping based on the host used. For example, if using the Core (Basic) host, refer to the figure below (with the corresponding pins highlighted in red) for configuration:

   

   Then, adjust each DIP switch as shown in the figure below:

   • NSS: Four options (choose one among G15, G12, G5, or G0)
   • BUSY: Two options (choose either G36 or G2)
   • RST: Two options (choose either G25 or G13)
   • IRQ: Three options (choose one among G35, G34, or G26)
   

   Example: If selecting the pins for the Core host, the DIP switch positions would be set as follows: NSS → G12, BUSY → G2, RST → G25, IRQ → G35.

3. Reconnect and Power On
   After setting the DIP switches, reconnect the module and power it on for further use.

4. Precautions

• Power Off: Always ensure the module is powered off before adjusting the DIP switches.
• Correct Configuration: Verify that the DIP switch settings correspond correctly to the host pins to avoid pin conflicts.

5. Summary

By using DIP switches, the Module LoRa868 v1.2 can flexibly switch key pin configurations on different host platforms, thus avoiding pin conflicts when stacked. Please refer to this manual and adjust the settings according to the host model and your specific needs to ensure stable system operation.
