  • BOOT switch
  • MicroSD card slot (when using Lite CM4 only)
  • USB-C power/programming port
  • Full-size HDMI port (supports 4K 30FPS)
  • 4-pin fan header (ideal fan option here!)

All of this along with a 5" display with a respectable 800x480 resolution with 5-point capacitive touch!

  • The USB SLAVE interface is used to burn the image and cannot be used as an OTG interface.

  • Onboard default 4-way USB 2.0 interface.
  • Supports PoE via 4-pin header, additional PoE HAT is required for PoE
  • The display requires a driver
