LORDWORLD 2-CH Isolated CAN Bus HAT for Raspberry Pi Jetson Nano

SKU CH-9WR3-B4BVA

Adds dual isolated CAN channels to Raspberry Pi or Jetson Nano boards via 40-pin GPIO with MCP2515 and SN65HVD230 chips

  • Dual-channel CAN communication via MCP2515 and SN65HVD230 chips
  • Power isolation removes need for separate isolated supply
  • Signal isolation improves noise immunity and safety
  • 7–36 V input powers both Pi and HAT simultaneously
  • Jumper-selectable 120 Ω termination and 3.3 V/5 V logic levels

Dual-Channel CAN HAT for Pi and Jetson

This expansion HAT adds two isolated CAN channels to any Raspberry Pi series board or Jetson Nano through the standard 40-pin GPIO header. It uses an MCP2515 controller paired with an SN65HVD230 transceiver on each channel for reliable bus communication. The board targets developers building automotive, industrial or robotics networks that need redundant or separate CAN links.

Stackable design with wide-range power input

The HAT mounts directly on the GPIO header and can be stacked with other compatible HATs to increase channel count. An onboard terminal accepts 7 to 36 V and powers both the HAT and the host board, removing the need for a separate supply. Jumpers select 3.3 V or 5 V logic levels and enable or disable the 120 Ω termination resistor per channel.

Isolation and protection built in

A unibody isolated supply and digital isolator separate the CAN side from the host, improving noise immunity and safety. An SM24CANB TVS diode clamps transient voltages and ESD events on the bus lines. These features mean the hardware handles harsh electrical environments without extra shielding or external protection circuits.

Questions about this item

How many CAN channels can the dual MCP2515 and SN65HVD230 chipset handle simultaneously?

The HAT provides two independent CAN channels using the combined MCP2515 controller and SN65HVD230 transceiver pair.

What is the wide input voltage range for the onboard external power terminal that can also supply the host board?

The terminal accepts 7 to 36 V and can power both the HAT and the attached Raspberry Pi or Jetson Nano.

Which host boards does the 40-pin GPIO header align with for direct stacking?

It matches the standard 40-pin header on Raspberry Pi series boards and the Jetson Nano.
