RS485 & CAN Shield Expansion Board for Raspberry Pi 4 Model B/3B+/3B/2B/Zero/Zero W

Overview RS485CAN Shield is an industrial communication module for Raspberry Pi there are 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 scene Features Compatible with Raspberry Pi 4 Model B 3B 3B 2B Zero Zero W Only a small amount of GPIO are used and the rest pins allow to work for other expansion function please refer to RS485 CAN Shield GPIO MAPPower 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 Packing List 1 x Shield4 x F M Spacer 2 5 16 64 x Screw 2 5 6
