Green circuit board with 40-pin GPIO header, screw terminals and pin headers

LORDWORLD

LORDWORLD 2-Ch RS485 1-Ch CAN HAT (B) development board

SKU CH-FD3Y-0GYCB

Expands a Raspberry Pi with one CAN and two RS485 channels using isolated SPI interfaces and an 8-to-28-volt supply that also powers the Pi

  • Standard 40-pin header fits Raspberry Pi boards
  • Single CAN channel via MCP2515 SPI-to-CAN conversion
  • Dual RS485 channels using SC16IS752 and SP3485
  • 8–28 V wide-range supply powers Pi and HAT
  • Isolated power and digital signals with TVS, fuse and 120 Ω jumper

2-Channel RS485 and 1-Channel CAN HAT

The LORDWORLD expansion board adds one CAN channel and two RS485 channels to any Raspberry Pi with a 40-pin GPIO header. It targets makers and engineers building industrial or automotive communication links on a single-board computer.

Isolated power and signal paths

Onboard unibody power-supply isolation and digital isolation deliver stable voltage and jam-proof signalling without an extra isolated supply. A wide 8~28 V input feeds both the HAT and the host Pi, while TVS diodes, a resettable fuse and protection diodes guard against surges and over-voltage events.

SPI host interface and flexible wiring

The MCP2515 and SC16IS752+SP3485 bridges convert SPI to CAN and RS485 respectively, with broken-out SPI control pins for alternative host boards. A jumper-selectable 120 Ω termination resistor and mixed terminal-block and pin-header connectors simplify bus wiring in the field.

Perguntas sobre este artigo

Will the 40PIN header on this HAT align with the GPIO on my Raspberry Pi 2B or Zero W?

The board uses the standard Raspberry Pi 40PIN GPIO extension header, so it fits Pi 4B, 3B+, 3B, 2B, B+, A+, Zero W and Zero WH models directly.

How can I confirm the CAN channel is communicating after I install the HAT?

The MCP2515 controller converts SPI to CAN; check the SPI bus for the MCP2515 device and verify CAN frames appear on the bus using standard Linux tools such as candump.

Does the box include the 8–28 V power supply or terminal cables, or must I source them separately?

The HAT ships with onboard terminals and pin headers for wiring; the wide-voltage power input and any external power supply or cables are not included and must be provided separately.
