Raspberry Pi RS485 CAN HAT (B) User Guide

 NoteDo not include Raspberry Pi, Please Buy alone.


  • Based on Raspberry Pi 40PIN GPIO interface design, suitable for Raspberry Pi series motherboards
  • 1 CAN, using the controller MCP2515, with CAN transceiver, can realize SPI to CAN
  • Equipped with two channels of RS485, using SC16IS752 and SP3485 dual-chip combination scheme, can realize SPI to RS485
  • On-board power conversion circuit, support 8~28V wide voltage power supply, can supply power to Raspberry Pi at the same time
  • On-board integrated power isolation, which can provide stable isolation voltage, and no additional power supply is required at the isolation end
  • On-board integrated digital isolation for signal isolation, high reliability, strong anti-interference, and low power consumption
  • On-board TVS (transient voltage suppression tube), which can effectively suppress surge voltage and transient peak voltage in the circuit, lightning protection and anti-static
  • On-board resettable fuses and protection diodes ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve shock resistance
  • On-board 120Ω termination resistor, enabled by jumper cap settings
  • There are two wiring methods of on-board terminals and pin headers, making wiring more convenient
  • Lead out SPI control interface for easy access to other controllers for control
