Isolated RS485 CAN HAT (B), Standard Pi 40PIN GPIO Header, Compatible with Raspberry Pi Series Boards, Bulit-in Multi Protections. It Enable Isolated And Stable RS485 And CAN Capability For Your RPi.
Features
Expand 1-Ch CAN and 2-Ch RS485---1-Ch CAN,: adopts MCP2515 controller and CAN transceiver, converts SPI to CAN.
2-Ch RS485: adopts SC16IS752+SP3485 dual-chip combination, converts SPI to RS485.
Industrial Grade Isolation Protection---Onboard unibody power supply isolation, providing stable isolated voltage, no extra power supply required for the isolated terminal.
Onboard unibody digital isolation, for isolating the signal, reliable and jamproof, low power consumption.
Onboard power conversion circuit, supports 8~28V wide voltage power supply, can power the RPi at the same time.
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, light-ning-proof & anti-electrostatic.
Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance.
Onboard 120O terminal resistor, configured by jumper.
Onboard terminals and pin headers, more convenient connection.
Breakout SPI control pins, for connecting with host control boards.
