Waveshare RS485 CAN Expansion Board for Jetson Nano w/ Digital Isolation

Description

The Waveshare RS485 CAN Expansion Board is a professional-grade interface module engineered to extend the connectivity of the NVIDIA Jetson Nano developer kit into industrial environments. It provides electrically isolated and protected serial communication channels, essential for reliable operation in settings with electrical noise, long cable runs, or varying ground potentials.

At its core, the board integrates two key industrial protocols. The RS485 interface, driven by the SP3485 transceiver, offers robust half-duplex communication over long distances, ideal for connecting sensors, actuators, or Modbus devices. The CAN bus interface, implemented with the MCP2515 controller and SIT65HVD230DR transceiver, is the standard for automotive and real-time control networks. Both interfaces are buffered and isolated to protect the sensitive Jetson Nano host from external electrical disturbances, ensuring data integrity and system longevity.
