Module LoRa868 v1.2 DIP Switch Instruction Manual

1. Overview

To avoid pin conflicts when stacking the Module LoRa868 v1.2 with the host, the module uses a DIP switch to flexibly switch the connection of key pins. Users can adjust the pin configuration according to the host being used (e.g., Core/Basic, Core2, or CoreS3), ensuring 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 below:

2.2 Pinmap

The available pin mappings vary depending on the host. The key pin configurations are as follows:

• For example, when using the Module LoRa868 v1.2 with Core (Basic), refer to the first row for the Core pin mapping:
  • RST: Choose either G25 or G13
  • BUSY: Choose either G36 or G2
  • NSS: Choose from G15, G12, G5, or G0
  • IRQ: Choose from G35, G34, or G26

3. DIP Switch Switching Operation

Please follow these steps to adjust the DIP switch settings:

1. Power Off
   Ensure the module is powered off before adjusting the DIP switch to avoid damaging the hardware.

2. Set the DIP Switch
   Select the appropriate pin mapping based on the host in use.

   

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