This is a 2-Channel Isolated CAN Bus Expansion HAT for the Raspberry Pi, offering multiple onboard protection circuits to create an isolated and stable CAN Bus capability for your Raspberry Pi. Features * 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 communication safer, more stable and improves anti-interference * Onboard TVS (Transient Voltage Suppressor) diode, provides ESD protection and transient peak voltage protection * Onboard voltage translator, select 3.3V/5V operating voltage by jumper * Onboard 120Ω terminal resistor, configured by jumper * Breakout SPI control pins, for connecting with host control boards like STM32/Arduino Specifications * CAN Controller: MCP2515 * CAN Transceiver: SN65HVD230 * Control Bus: SPI * Power Supply Voltage: 5V * Logic Level Voltage: 3.3V/5V * Dimensions: 65×56.5mm Resources * User Guide and Wiki: https://www.waveshare.com/wiki/2-CHCANHAT https://elecena.pl/product/22719135/2-channel-isolated-can-hat-for-raspberry-pi 2023-03-07 https://elecena.pl/product/22719135/2-channel-isolated-can-hat-for-raspberry-pi 2023-12-27 https://elecena.pl/product/22719135/2-channel-isolated-can-hat-for-raspberry-pi 2024-09-19 https://elecena.pl/product/22719135/2-channel-isolated-can-hat-for-raspberry-pi 2024-11-29 https://elecena.pl/product/22719135/2-channel-isolated-can-hat-for-raspberry-pi 2024-11-30 https://elecena.pl/product/22719135/2-channel-isolated-can-hat-for-raspberry-pi 2025-08-05 https://elecena.pl/product/22719135/2-channel-isolated-can-hat-for-raspberry-pi 2025-11-28 https://elecena.pl/product/22719135/2-channel-isolated-can-hat-for-raspberry-pi 2025-11-29
