Description

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.
