Product Technical Information
Technical Details
The Waveshare SN65HVD230 CAN Board is an accessory board for connecting compatible microcontrollers to a Controller Area Network (CAN). It integrates the SN65HVD230 3.3V CAN transceiver, providing the physical-layer interface between a CAN controller and the differential CAN bus.
The board is designed for 3.3V systems and supports CAN signaling rates up to 1 Mbps. The SN65HVD230 is compatible with the ISO 11898-2 high-speed CAN physical layer and is intended for applications such as industrial automation, robotics, sensors, drive systems, and automotive electronics.

Important Notes
The SN65HVD230 is a CAN physical-layer transceiver, not a standalone CAN controller. Your microcontroller or host system needs CAN-controller functionality to generate and process CAN protocol messages.
For a conventional CAN bus, a twisted-pair bus with appropriate 120Ω termination at the two physical ends is typically used. Keep branch/stub connections short to help minimize signal reflections.
Do not short the CANH and CANL pins. Waveshare specifically warns against this condition.
