## Description

The **2-CH CAN HAT+** is a 2-Channel CAN bus expansion HAT designed for Raspberry Pi. Supports expanding multiple CAN channels by stacking with the [2-CH CAN HAT.](https://core-electronics.com.au/2-channel-isolated-can-expansion-hat-for-raspberry-pi-dual-chips-solution-1.html) Adopts HAT+ standard design, compatible with Raspberry Pi series boards such as Raspberry Pi 5/4/3/Zero. Onboard various protection circuits, including electrical isolation to make communication more safe and reliable. Supports wide range voltage input of 7~36V, suitable for industrial applications.

- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards / Jetson Nano
- Adopts MCP2515 and SN65HVD230 dual chips combined solution, allows 2-channel CAN communication
- Onboard unibody power supply isolation, providing stable isolated voltage, requires no extra power supply for the isolated terminal
- Onboard digital isolator, signal isolation makes the communication more safe and stable, and better anti-interference
- Onboard external power supply terminal, supports 7~36V wide voltage power input, supports powering the Pi and the HAT at the same time
- Onboard SM24CANB 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 120O terminal resistor, configured by jumper
- Breakout SPI and I2C control pins, for connecting with other host control boards
- Comes with online development resources and manual (examples in Python/C)
