Isolated RS485 CAN HAT (B) For Raspberry Pi, 2-Ch RS485 and 1-Ch CAN, Multi Protections
Isolated RS485 CAN HAT (B) for Raspberry Pi
2-Ch RS485 and 1-Ch CAN, SPI communication
Bulit-in power supply isolation, magnetical isolation, and TVS diode, etc.
Features at a glance
- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
- 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
- Onboard power conversion circuit, supports 8~28V wide voltage power supply, can power the Raspberry Pi at the same time
- 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 TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & 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 120Ω terminal resistor, configured by jumper
- Onboard terminals and pin headers, more convenient connection
- Breakout SPI control pins, for connecting with host control boards
