LORDWORLD 2-Channel Isolated CAN Bus HAT 2515 230

SKU CH-SW1T-K16V1

Adds two isolated CAN channels to Raspberry Pi or Jetson Nano boards using MCP2515 and SN65HVD230 chips with 736 V power input and 120 Ω termination

  • Dual CAN channels via MCP2515 and SN65HVD230
  • Isolated power and signals for stable communication
  • 736V wide-range input powers Pi and HAT
  • 3V or 5V logic selectable by jumper
  • 120Ω termination configurable by jumper

Two-Channel CAN Bus HAT for Raspberry Pi

This HAT adds dual isolated CAN interfaces to Raspberry Pi 5, 4B, 3B+, Zero and Jetson Nano boards via the standard 40-pin GPIO header. It targets developers building automotive, industrial or robotics prototypes that need two independent CAN networks on a single compact add-on. Online resources include Python and C examples for rapid integration.

Isolated power and signal paths

Onboard power-supply isolation delivers a stable isolated voltage without an extra supply, while a digital isolator separates signal grounds for noise immunity. An SM24CANB TVS diode clamps transients on the bus lines. Jumpers let you select 3.3V or 5V logic levels and enable or disable the 120-ohm termination resistors. Broken-out SPI and I2C pins allow stacking additional boards.

Dual MCP2515 controllers

The board pairs two MCP2515 CAN controllers with two SN65HVD230 high-speed transceivers, providing two fully independent CAN channels. The external power terminal accepts a 736V wide-range input and can supply both the HAT and the host board simultaneously. This dual-chip architecture is the deciding factor for applications requiring simultaneous dual-bus operation.

Questions sur cet article

What CAN controller and transceiver chips does the HAT use for its two channels?

It uses the MCP2515 CAN controller and SN65HVD230 transceiver in a dual-chip solution for two independent CAN channels.

How does the HAT mount to a Raspberry Pi or Jetson Nano?

It connects via the standard 40-pin GPIO extension header and aligns with the board mounting holes.

How do I enable the onboard 120-ohm termination resistors for each CAN channel?

Set the corresponding jumper for each channel to activate the 120-ohm terminal resistor on the bus.
