Raspberry Pi 4B/3B +/Zero W RS485 CAN Expansion Board CAN Module UART Communication Module -79251

Overview:

The RS485 CAN HAT will enables your Pi to communicate with other devices stably in long-distance via RS485/CAN functions.

Features:

• Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+

• CAN function, onboard CAN controller MCP2515 via SPI interface, onboard transceiver SN65HVD230

• RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard transceiver SP3485

• Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit for RS485 transceiving, lightning-proof & anti-electrostatic

• Reserved control pins, allows to work with other control boards

• Comes with development resources and manual (examples in wiringPi/python)
