RS485 CAN HAT for Raspberry Pi – Enables Stable Long-Distance Communication The RS485 CAN HAT enables your Raspberry Pi to communicate stably with other devices over long distances using RS485 and CAN protocols. 1. Standard 40-pin GPIO extension header, compatible with Raspberry Pi series boards 2. CAN functionality: onboard CAN controller MCP2515 via SPI interface, onboard transceiver SN65HVD230 3. RS485 functionality: controlled via UART, half-duplex communication, supports automatic TX/RX control without additional programming, onboard transceiver SP3485 4. Onboard transient voltage suppressor (TVS), effectively suppresses surge voltage and transient spike voltage in the circuit for RS485 reception, providing protection against electrostatic discharge 5. Reserved control pins allow integration with other control boards Operating voltage: 3.3V Mounting hole size: 3.0 mm Color: Blue Material: PCB Dimensions: 65 mm × 30 mm Package Contents: - 1 × RS485 CAN HAT - 1 × Raspberry Pi screw pack (2 pcs) Note: Lighting conditions and display settings may cause slight color variation between the image and the actual product. Measurement tolerance: ±1–3 cm.
