RS485 And CAN Module

• RS485&CAN Module is an industrial communication module for Raspberry Pi, on board 2*RS485 Bus and 1*CAN Bus communication interface via SPI interface.
• CAN bus and RS485 bus powered through separated isolation power module, signal between the transceiver and the controller is isolated , ESD protection for the communication port, ensure your raspberry pi can be used in more strictly industrial sites.

Features

• Compatible with Raspberry Pi Zero/Zero W/2B/3B/3B+. Only a small amount of GPIO are used and the rest pins allow to work for other extended function
• Power supply and signal isolation, Build-in surge and ESD protection.
• CAN function, onboard CAN controller MCP2515 via SPI interface, onboard high speed CAN transceiver, onboard digital isolation ADUM1201BRZ, Communication Rates 20Kbps-1Mpbs can be programmed arbitrarily.
• RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard SPI to RS485 SC16IS1752. Electrical data isolation ADM2483.
• On board individual 120 Ohm terminal resistance, Impedance matching and guarantee the ability to drive.
