Features At A Glance

  • Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
  • 1-Ch CAN, adopts MCP2515 controller and CAN transceiver, converts SPI to CAN
  • 2-Ch RS485, adopts SC16IS752+SP3485 dual-chip combination, converts SPI to RS485
  • Onboard power conversion circuit, supports 8~28V wide voltage power supply, can power the Raspberry Pi at the same time
  • Onboard unibody power supply isolation, providing stable isolated voltage, no extra power supply required for the isolated terminal
  • Onboard unibody digital isolation, for isolating the signal, reliable and jamproof, low power consumption
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
  • Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
  • Onboard 120Ω terminal resistor, configured by jumper
  • Onboard terminals and pin headers, more convenient connection
  • Breakout SPI control pins, for connecting with host control boards
