RS-485 CAN HAT för Raspberry Pi

RS485 is one of the most robust wired serial communication protocol that can support distance upto 1200 meters (4000 ft) while CAN (Controller Area Network) is used in automotive that offer high immunity to noise in cars.

This RS485/CAN HAT will enables your Raspberry Pi to communicate with other devices stably in long-distance via RS485/CAN protocol. Yes, this board support both RS485 and CAN, birectional communication. You can use both the standards/protocols at the same time because each of them uses different peripheral for communication. CAN controller uses SPI while RS485 uses UART from Raspberry Pi.

Features
Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/A
+/3B/3B+
CAN function, onboard CAN controller MCP2515 via SPI interface, with transceiver SN65HVD230
RS485 function, controlled via UART, half-duplex communication, with transceiver SP3485
Both protocols can be utilzed at the same time because:
CAN controller uses SPI interface
RS485 transceiver uses UART interface
Reserved control pins, allows to work with other control boards
Comes with development resources and manual (examples in wiringPi/python)
Stack perfectly on Raspberry Pi Zero board and compatible wtih Raspberry Pi 3B/3B+
