Waveshare Isolated RS485 CAN HAT for Raspberry Pi

1. Standard Raspberry Pi 40PIN GPIO extension header, support Raspberry Pi series boards
2. 1-Ch CAN, adopt MCP2515 controller and CAN transceiver, convert SPI to CAN
3. 2-channel RS485, adopt SC16IS752 + SP3485 dual-chip combination, convert SPI to RS485
4. Onboard power conversion circuit, support 8~28V wide voltage power supply, can power the Raspberry Pi at the same time
5. Integrated unibody power supply isolation, providing stable isolated voltage, no additional power supply is needed for the isolated terminal
6. Onboard unibody digital isolation, to isolate the signal, reliable and jam-proof, low power consumption
7. Built-in TVS (transient voltage suppressor), effectively suppress the surge voltage and transient surge voltage in the circuit, lightning-proof and anti-electrostatic
8. Built-in resettable fuse and protection diodes, ensures stable current/voltage outputs, provides over-current/over-voltage protection, improves shock resistance
9. Built-in 120Ω terminal resistor, configured via jumper
10. On-board terminals and pin headers, more convenient connection
11. SPI breakout control pins, for connection to host control boards
