This is a 2-Channel CAN bus expansion HAT designed for Raspberry Pi, supports CAN2.0, features multi onboard protection circuits, high anti-interference capability, and stable operation. It suits for fields such as automotive devices or industrial automation.CAN module could process packets transmit/receive on CAN bus. Packets transmit: first store packet to related buffer and control register. Use SPI interface to set the bits on control register or enable transmit pin for transmitting. Registers could be read for detecting communication states and errors. It will first check if there are any errors of packets detected on CAN bus, then verify it with filter which is defined by user.
- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
- Adopts MCP2515 and SN65HVD230 dual chips combined solution, allows 2-channel CAN communication
- Integrated power isolation, providing stable isolated voltage, requires no extra power supply for the isolated terminal
- Onboard digital isolator, signal isolation makes the communication more safe, more stable, and better anti-interference
- Onboard TVS (Transient Voltage Suppressor) diode, provides ESD protection and transient peak voltage protection
