RS485 CAN Expansion Board

Designed for Jetson Nano

 

Features At A Glance
  • Standard 40PIN GPIO extension header, supports direct attaching to Jetson Nano
  • Onboard CAN controller MCP2515 via SPI interface, matching with SIT65HVD230DR transceiver
  • Features RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard transceiver SP3485
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit for RS485 transceiving, lightningproof & anti-electrostatic
  • Onboard digital isolation chip, safer signal isolation communication and better stability and anti-interference
  • Reserved control pins, allows to work with other control boards
  • Comes with development resources and manual (examples in python)
