Waveshare 27338 - 2-Channel Isolated CAN Bus Expansion HAT For Raspberry Pi, Dual Chips Solution, Stackable Design For Expanding Multiple CAN Channels, Built-In Multi Protections, Raspberry Pi HAT Features 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 or 2-CH CAN FD HAT. 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 120Ω 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) Specifications CAN controller MCP2515 Control bus SPI Power supply method External power supply terminal or Raspberry Pi GPIO Terminal voltage input DC 7~36V operating voltage 5V LOGIC LEVEL 3.3V/5V Dimensions 65.0 × 56.5mm What can it do?
