Features CAN and RS485 functions with automatic control
Includes 120Ω terminal resistor and TVS for surge protection
Comes with online resources and manual for development
The Waveshare RS485 CAN HAT for Raspberry Pi facilitates stable long-distance communication between Raspberry Pi and other devices. It integrates a standard 40PIN GPIO extension header, supporting Raspberry Pi series boards. The device features a CAN function with an onboard MCP2515 controller via SPI interface and a SIT65HVD230DR transceiver. Additionally, it includes an RS485 function controlled via UART, supporting half-duplex communication with automatic TX/RX control. The HAT is equipped with a 120Ω terminal resistor for RS485 and CAN interfaces, enabled via a DIP switch, and a transient voltage suppressor for surge protection.
