Module LoRa868 v1.2 DIP Switch Documentation

1. Feature Overview

To avoid pin conflicts when stacking Module LoRa868 v1.2 with the host, the module uses four DIP switches to flexibly reassign key pins.

• The four function pins NSS, BUSY, RST, IRQ can be assigned to different GPIOs via the DIP switches.
• Compatible with various M5Stack hosts: Core (Basic), Core2, CoreS3, etc.
• Users can adjust the pin mappings as needed to ensure stable system operation.

2. DIP Switch Overview

2.1 Physical Location of DIP Switches

The four DIP switches are located on the bottom of the module, as shown in the red frames below.

2.2 Pin Mapping Table

Depending on the host, the available mappings for the key pins are as follows:

• For example, when using Module LoRa868 v1.2 with a Core (Basic) host, refer to the first row for the mapping:

  • NSS: choose one of G15, G12, G5, or G0
  • BUSY: choose one of G36 or G2
  • RST: choose one of G25 or G13
  • IRQ: choose one of G35, G34, or G26

3. DIP Switch Configuration Example

Below is an example configuration for Core (Basic) + Module LoRa868 v1.2, showing how to set the four DIP switches:

• After setting the DIP switches, reconnect the module and apply power for use.
