RS485 CAN Expansion Board for Jetson Nano

RS485 CAN Expansion Board for Jetson Nano, Digital Isolation, Built-In Protection Circuit

Features

• 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)
