LORDWORLD 2-Channel Isolated RS485 Expansion HAT development board

SKU CH-Z0ZD-FZD62

Adds two isolated RS485 channels to Raspberry Pi via SPI at up to 921600 bps with TVS, fuse and diode protection

  • Two isolated RS485 channels for industrial serial links
  • SC16IS752 plus SP3485 bridge converts SPI to RS485 at 921600 bps
  • DIP switch selects manual or automatic transceiver mode
  • Onboard TVS diodes, auto-recovery fuse and protection diodes guard against surges
  • 40-pin GPIO header fits Raspberry Pi series; breakout pins also suit Arduino

2-Channel Isolated RS485 HAT for Raspberry Pi

This expansion HAT adds two isolated RS485 ports to Raspberry Pi boards via the standard 40-pin GPIO header. It uses an SC16IS752 and SP3485 chip combination to convert SPI signals to RS485 at up to 921600bps. Onboard TVS diodes, an auto-recovery fuse and protection diodes guard against surges and over-current events. Status LEDs show power and transceiver activity, and development resources include C and Python examples.

Suits Pi projects needing dual RS485 links

Makers building Modbus networks, industrial sensor arrays or long-distance serial buses will benefit from the dual channels and hardware isolation. The board also breaks out SPI control pins for Arduino compatibility. Buyers who need more than two RS485 channels or a different physical interface should look at other expansion options.

SPI-to-RS485 conversion up to 921600bps

The SC16IS752+SP3485 solution handles the protocol translation and sets the maximum data rate. A DIP switch selects manual or automatic transceiver control for each channel. This speed ceiling is the key figure to verify against your bus timing requirements before purchase.

Otázky k tomuto produktu

How can I confirm the HAT is communicating correctly after connecting it to my Raspberry Pi?

The onboard LEDs show power and transceiver activity, and the development examples in C and Python let you verify SPI-to-RS485 data flow at up to 921600bps.

What accessories are included and what must I source separately?

The board ships with the 40PIN GPIO extension header and a manual; you need to provide a Raspberry Pi series board, Arduino board if using the breakout SPI pins, and your own RS485 cabling.

Which configuration should I select for manual versus automatic transceiver control?

Use the DIP switch on the HAT to choose between manual or automatic transceiving modes for the dual SC16IS752+SP3485 channels.
