Main features of RS485 CAN module for Nvidia Jetson Nano

  • Standard 40-pin GPIO connector of the Nvidia Jetson Nano minicomputer
  • Built-in CAN MCP2515 controller available via SPI interface, compatible with SIT65HVD230DR transceiver
  • RS485 interface controlled by UART, half-duplex communication, support TX / RX automatic control without programming, built-in SP3485 transceiver
  • Built-in TVS (Transient Voltage Suppressor) protection, effectively suppresses overvoltage and transient voltage in the circuit for RS485, anti-electrostatic
  • Built-in digital isolation chip, safe communication signal isolation, and better stability and anti-interference performance
  • Reserved control pins allow you to work with other boards

The manufacturer provides a user guide with sample program codes, making it easier to start working with the module.
