Industrial Isolated Interface Expansion Board

Suitable for Raspberry Pi 4B / 5,
expands 2x RS485 + 1x RS232 + 1x CAN FD + 1x CAN

RS232 / RS485 / CAN / CAN FD expansion board, front view

Features

The RS232 RS485 CAN Board is an industrial isolated interface expansion board designed for Raspberry Pi 4B / Raspberry Pi 5, provides a variety of industrial communication interfaces: 2x RS485, 1x RS232, 1x CAN FD, and 1x CAN, each with electrical isolation. Onboard lightningproof, anti-electrostatic protection, etc. for more secure and reliable communication.

Comes with industrial rail-mount enclosure for easy integration in industrial control applications. Provides sufficient internal space for users to stack other HATs or expansion boards, and reserved installation space of PCIe adapter board for Raspberry Pi 5, which is more convenient for further expansion.

  • Based on Raspberry Pi 40PIN GPIO header, suitable for Raspberry Pi 4B and Raspberry Pi 5
  • Adopts SC16IS752 and SP485 combination scheme, expands SPI to 2x RS485 interface
  • Adopts MCP2515 and SN65HVD230 combination scheme, expands SPI to 1x CAN interface
  • Adopts MCP2518FD and MCP2562FD combination scheme, expands SPI to 1x CAN FD interface
  • Adopts Raspberry UART and SP3232EEN combination scheme, expands UART to 1x RS232 interface
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection
  • Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
  • Onboard unibody power supply isolation, needs no extra power supply for the isolated terminal, provides stable current/voltage outputs of RS232, RS485, CAN, and CAN FD interfaces, and improves the anti-interference and anti-shock performance
  • Onboard digital isolation chip for safer signal isolation communication and better stability and anti-interference performance
  • Onboard external power supply screw terminal for 7~36V wide voltage power input, combines with Pi5 Connector Adapter (B) to power the Raspberry Pi and the expansion board at the same time
  • Onboard 120Ω terminal resistor, configured by jumper
  • Reserved interrupt resistor pad for flexible switching the interrupt pin if there is pin conflict when working with other HATs
  • Comes with online development resources and manual (examples for Raspberry Pi Python/C)
