Description

My name is CM4-ETH-RS485-BASE-B, which is an expansion board that can be used with Raspberry Pi Compute Module 4, and supports a 7-36V DC power supply and 5V DC-DC power supply of Typc-C interface. Onboard four isolated RS485 interfaces, 100M+1000M dual network ports, HDMI interface, two CSI interfaces, two USB interfaces, etc…

Applications: 

Suitable For Raspberry Pi Applications Requiring Multi-Channel RS485 Communication Or Other Industrial Context


Features: 

  1. Do not plug and unplug any device except USB and HDMI when it is powered on
  2. Confirm the fan voltage before connecting, only support 5V
  3. 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)
  4. 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.
  5. When CM4 is in normal use, it needs to provide a 5V 2A power supply for CM4. Otherwise, there may be problems such as automatic shutdown, frequency reduction, and so on.
  6. USB2.0 is closed by default, if you need to open it, you need to add dtoverlay=dwc2,dr_mode=host in config.txt

Packages Includes: 

1 x Waveshare Dual ETH Quad RS485 Base Board (B) for Raspberry Pi Compute Module 4
