The CM4-4G IO Board is a multi-function expansion board based on the Raspberry Pi Computer Module 4. It features a native Gigabit Ethernet, a 10/100Mbps USB extended Ethernet, a full-size HDMI-compatible interface supporting 4K output, two USB2.0 host interfaces, a 4G network card, and other GPIO.

Power is supplied through the USB-C interface. The Gigabit + 100M + 4G network structure is suitable for applications such as soft routers and gateways; it can also be used for applications such as 4K players that support remote updates.

It supports all series of CM4 core boards, CM4 without eMMC supports booting from a TF card, and CM4 with eMMC can be programmed through a USB-C port.

Hardware Overview

  • One 1Gbps original Ethernet, with all in one RJ45,better EMC/EMl;
  • One 100Mbps Ethernet;
  • Dual USB-A ports can be connected to USB devices such as keyboard and mouse;
  • One USB(1.25mm 4pin),The 1.25T 4pin internal USB connector is mux with the USB-A port;
  • One 4G LTE Module
  • One Nano SlM Card; (be based on 4G)
  • One voice function;(be based on 4G)
  • One standard-size HDMl-compatible output, supports up to 4K video output;
  • One TF card, support booting from TF for eMMC less CM4 ;
  • One USB Type-C power (5V3A) and eMMC program;
  • One FAN power (3.3V 2.54mm 2pin) (opt) ;
  • GPIO (include UART*1,12C*1,ADC*1,SPI*1,USB OTG,CM4 Reset lO and other 16pin GPIO);
  • 4G GPIO (include Debug UART and Reset) ;
  • Size:110mm*70mm;


Note: The 1.25T 4pin internal USB connector is mux with the USB-A port, if the 1.25T 4pin is used to connect the 4G module, the USB-A can not use anymore.



  • Support all Raspberry Pi Computer Module 4
  • Onboard dual USB 2.0 with an extra 1.25MM4Pin interface for more external ports
  • Powered by USB Type-C(5V/3A), with Cat 4 free drive 4G module
  • With rich I/O peripherals, more expandable
  • Affordable Powerful Features can be used in Software Router, Network appliances, IoT applications, Smart Homes, etc.
