Frequently Asked Questions

What is the primary function of the Waveshare 2-Channel Isolated CAN HAT?

This HAT provides two channels of isolated CAN bus communication for Raspberry Pi boards. It utilizes an MCP2515 CAN controller and an SN65HVD230 transceiver for each channel, ensuring robust and interference-free data exchange suitable for industrial and automotive environments.

How does this HAT ensure isolated communication and system protection?

The HAT integrates power isolation, digital isolators for signal integrity, and an SM24CANB TVS diode. These features collectively protect the Raspberry Pi from ground loops, voltage transients, and electrostatic discharge, making communication safer and more stable.

Can this HAT be used with microcontrollers other than Raspberry Pi?

Yes, although designed for Raspberry Pi, the HAT breaks out essential SPI control pins. This allows developers to connect it to other host control boards like STM32 or Arduino, enabling isolated CAN bus capabilities in a broader range of embedded projects.

How do I configure the logic level and terminal resistor on this HAT?

The HAT features onboard jumpers for configuring both the logic level and the 120Ω terminal resistor. Users can select between 3.3V and 5V logic levels to match their host controller, and enable/disable the terminal resistor as required by the CAN network topology.

What are the main components driving the CAN communication on this HAT?

The HAT employs a dual-chip solution: the MCP2515 acts as the standalone CAN controller, managing the CAN protocol, while the SN65HVD230 functions as the CAN transceiver, converting the CAN controller’s logic levels to the differential signals required for the CAN bus line.
