ETH RS485 Scheda di Base per Raspberry Pi Compute Module 4 CM4 Dual Quad Espansione, Integrata Gigabit Ethernet/100M Ethernet/4CH Isolata RS485/CSI/USB2.0/HDMI/FAN/Micro SD ecc.

Dual ETH quad RS485 base board designed for Raspberry Pi Compute Module 4, onboard standard CM4 socket and suitable for all variants of Compute Module 4 Onboard four isolated RS485 interfaces, 100M+1000M dual network ports, HDMI interface, two CSI interfaces, two USB interfaces and Fan header(only support 5V), etc. Supports 7-36V DC power supply and 5V DC DC power supply of Typc-C interface Do not plug and unplug any device except USB and HDMI when it is powered on. When CM4 is in normal use, it needs to provide 5V 2A power supply for CM4. Otherwise, there may be problems such as automatic shutdown, frequency reduction and so on The Type C interface can be used as a power supply or as a USB interface to burn the image (need to use the DIP switch to switch). in order to ensure the normal power supply of CM4, please do not connect other devices when using the Type C interface to burn the image
