2-Channel Isolated CAN Bus Expansion HAT For Raspberry Pi: Expand Reliable Multi-Channel CAN Communication with Superior Isolation
Unlock powerful, dual-channel CAN communication for your Raspberry Pi projects with the 2-Channel Isolated CAN Bus Expansion HAT. Designed to meet the growing needs of industrial automation, automotive diagnostics, and advanced robotics, this HAT integrates two independent CAN channels using the MCP2515 and SN65HVD230 chipset combo. Its stackable and compact design makes it ideal for Raspberry Pi Zero, 2B, 3B, 3B+, 4B, and the latest 5 model, ensuring compatibility across a broad range of applications.
This CAN HAT features onboard power and digital signal isolation, enhancing the safety and stability of data transmission even in electrically noisy environments. The inclusion of SM24CANB protection ensures defense against ESD and voltage transients. With onboard EEPROM for automatic configuration and jumper-selectable voltage (3.3V/5V), it’s designed for seamless integration and efficient deployment in demanding embedded systems.
