Waveshare Isolated RS232 / RS485 / CAN/CAN FD Expansion Board, Compatible with Raspberry Pi 5/ 4B, expands 2X RS485 + 1x RS232+ 1x CAN FD + 1x CAN, Extending NVME, ETH, USB, and 4G/5G, etc

Based on Raspberry Pi 40PIN GPIO header, suitable for Raspberry Pi 4B and Raspberry Pi 5 Adopts SC16IS752 and SP485 combination scheme, expands SPI to 2x RS485 interface ^^ Adopts MCP2515 and SN65HVD230 combination scheme, expands SPI to 1x CAN interface Adopts MCP2518FD and MCP2562FD combination scheme, expands SPI to 1x CAN FD interface ^^ Adopts Raspberry UART and SP3232EEN combination scheme, expands UART to 1x RS232 interface Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection ^^ Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance Onboard unibody power supply isolation, needs no extra power supply for the isolated terminal, provides stable current/voltage outputs of RS232, RS485, CAN, and CAN FD interfaces, and improves the anti-interference and anti-shock performance ^^ Onboard digital isolation chip for safer signal isolation communication and better stability and anti-interference performance Onboard external power supply screw terminal for 7~36V wide voltage power input, combines with Pi5 Connector Adapter (B) to power the Raspberry Pi and the expansion board at the same time ^^ Onboard 120 terminal resistor, configured by jumper Reserved interrupt resistor pad for flexible switching the interrupt pin if there is pin conflict when working with other HATs ^^
