LORDWORLD Dual ETH Quad RS485 Mini-Computer Base development board

SKU CH-M34V-8010Z

Base board adds dual Gigabit Ethernet and four RS485 ports to a Raspberry Pi CM4 with fan cooling and wall-mount holes

  • Dual Gigabit Ethernet ports enable redundant industrial networking
  • Four RS-485 channels support multi-device serial communication
  • Integrated cooling fan with vented airflow improves thermal performance
  • Wall-mount holes on two sides allow flexible installation
  • Precise cut-outs align with every Raspberry Pi CM4 connector

Dual ETH Quad RS485 Base Board

This development board integrates a Waveshare expansion module to provide dual Gigabit Ethernet ports and four RS485 channels for a Raspberry Pi Compute Module 4. It is designed for engineers and makers building industrial IoT gateways or automation controllers that require multiple isolated serial links. The CM4 module itself is not included and must be sourced separately.

Sustained Load Thermal Management

A cooling fan is included and works with airflow vents to dissipate heat during continuous operation. This active cooling helps maintain stable temperatures when the CM4 handles persistent network traffic and multi-channel serial communication workloads. The enclosure design supports this airflow path to prevent throttling in demanding edge-computing scenarios.

Installation Alignment And Mounting

Precise cut-outs with clear labels align exactly with each connector, reducing wiring errors during assembly. Wall-mount holes on two sides allow secure fixed installation in cabinets or on machinery panels. Buyers needing wireless connectivity or additional high-speed storage interfaces will not find those features on this board.
