Designed for Raspberry Pi, support Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+/4B/5. ^^ Standard HAT+ design, with onboard EEPROM chip. ^^ Adopts MCP2515 and SN65HVD230 dual-chip solution, allowing 2-channel CAN communication. ^^ Integrated power isolation, providing stable isolated voltage, requires no extra power supply for the isolated terminal. ^^ Onboard digital isolation chip, signal isolation communication is safer, more stable, and better anti-interference.
