LORDWORLD

LORDWORLD 2-Channel RS485 Module for Raspberry Pi Pico SP3485

SKU CH-94VX-ZFGX0

Adds two RS485 channels to a Raspberry Pi Pico via UART using the SP3485 transceiver

  • Dual RS485 channels expand industrial connectivity for Raspberry Pi Pico
  • SP3485 transceiver enables reliable UART-to-RS485 signal conversion
  • Standard Pico header ensures direct mounting without extra wiring
  • Development resources include C/C++ and MicroPython examples for faster integration
  • Supports full Raspberry Pi Pico series for broad compatibility

Dual-Channel RS485 HAT

This LORDWORLD module adds two RS485 ports to any Raspberry Pi Pico series board through the standard 40-pin header. It uses the SP3485 transceiver to convert the Pico UART signals into balanced differential pairs for long-distance serial communication. Development resources and manuals are included with C/C++ and MicroPython examples.

Makers needing industrial buses

The board suits developers who want to connect Modbus sensors, PLCs or multi-drop networks to a Pico without designing their own level-shifting circuitry. It is not for projects that require CAN bus, Ethernet or wireless interfaces, nor for builds that need more than two RS485 channels.

SP3485 transceiver choice

The on-board SP3485 chip determines the electrical characteristics of every RS485 link, including driver output levels and receiver sensitivity. Selecting this module means accepting the transceiver’s specified common-mode range and data-rate limits for the whole system.

Questions about this item

How do I install the module on my Raspberry Pi Pico and which orientation mistake should I avoid?

Align the standard Pico header pins with the board’s socket and press straight down; reversing the board swaps the UART pins and stops communication.

What maintenance will the SP3485 transceiver need over time?

The SP3485 is a solid-state transceiver with no moving parts; keep terminals clean and check screw-terminal torque if vibration is present.

What limit appears first during sustained high-traffic RS485 use?

The UART baud-rate ceiling on the Pico becomes the bottleneck before the SP3485 reaches its thermal or signal-integrity limits.
