PIR motion sensor compatibility with LAN W5500 Proto Module

  • Hi there,

    I'm trying to connect a PIR motion Sensor to a core device which is connected to the LAN W5500 Proto Module for POE. The issue is the PIR motion sensor uses port B which is removed when the LAN device is added. I'm wondering if there is a another way I can connect the PIR device.


  • Hello @btrex

    not sure I understand why the LAN module removes port B. Do you mean the LAN module uses the GPIOs normally used for port B?

    Anyways, if you are using an M5Core2 device this module might help.

    And for an M5Stack device the bus module might be helpful as it exposes all pins.
