  Onboard resources


  • CM4 connector: connect CM4

  • CM4 working status light: used to judge whether CM4 is working

  • MP28164: DC buck-boost chip

  • Power supply selection: the resistor on the left - direct power supply; the resistor on the right - power supply after passing through the DC buck-boost chip (default)

  • IO level selection: select the IO level of CM4 (3.3V is selected by default)

  • CM3 interface: used to connect to the CM3 backplane
