Description
The "CM4-Dual-ETH Base" development board from Waveshare is based on the ,Raspberry Pi Compute Module 4 and has two Ethernet ports that ensure a reliable network connection for IoT devices and network applications.
In addition to the Ethernet ports, the CM4-Dual-ETH Base Board offers a variety of interfaces including USB 2.0, USB 3.0, HDMI, MIPI DSI and CSI, GPIO pins and more. It is equipped with a Gigabit Ethernet port and a 10/100 Mbps Ethernet port, each with a separate PHY. Compatible with various operating systems such as Linux and Android, the board is an ideal platform for developers and engineers to develop and test their applications that require a stable network Connection.
