Information

RS485 CAN HAT For Raspberry Pi, Allows Stable Long-Distance Communication

Overview

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

Features

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
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)
