RS485 CAN HAT For Raspberry Pi, Allows Stable Long-Distance Communication

Overview

The RS485 CAN HAT will enables your Pi to communicate with other devices stably in long-distance via RS485/CAN functions.

Features

  • Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
  • CAN function, onboard CAN controller MCP2515 via SPI interface, onboard transceiver SN65HVD230
  • 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, lightning-proof & anti-electrostatic
  • Reserved control pins, allows to work with other control boards
  • Comes with development resources and manual (examples in wiringPi/python)

Specifications
