Product information

Description

The Joy-IT USB to RS485 Converter SBC-ttl-rs485 is a compact interface adapter that connects a USB-A port to a 2-wire RS485 network. Designed for integration with Raspberry Pi, Arduino and other single-board computers or microcontroller systems, the adapter provides a simple USB 2.0 connection for industrial serial communication and sensor networks. The unit is enclosed in a black housing and supplied with a cable described as 0 m, intended for direct plug-and-play use where a short or external wiring solution is required.

Advantages

This converter offers a straightforward USB-to-RS485 bridge that requires minimal setup and supports reliable differential serial communication over two wires. Its compact form factor and USB-A connectivity make it suitable for quick prototyping and installation in constrained spaces. The device is compatible with common development platforms and supports integration into existing RS485 device-control systems without the need for additional transceiver modules.

Suitable for

  • Connecting Raspberry Pi or Arduino boards to RS485 sensor networks
  • Industrial serial communication and device control over RS485
  • Prototyping and testing of Modbus RTU and other RS485-based protocols
  • Short-distance communication setups and on-desk laboratory use

Key specifications

  • Interface: USB 2.0 Type-A to 2-wire RS485 differential pair
  • Cable: supplied cable listed as 0 m (adapter intended for direct plug-in or external wiring)
  • Signal levels: TTL/RS485-compatible transceiver for differential serial lines
  • Power: powered via USB port (bus-powered device)
  • Housing: compact, black enclosure suitable for desk or panel mounting
  • Compatibility: works with common SBCs, microcontrollers and serial communication software

How to use

Plug the USB-A connector into a USB port on the host system; the converter will draw power from the USB bus. Connect the RS485 A and B differential wires to the two-wire terminal or cable end of the RS485 network, ensuring proper polarity for communication. Install any required drivers or configure the host operating system serial port settings as needed for your platform. Configure baud rate, parity and stop bits in the host application to match the RS485 device network. For Modbus or other protocol use, set the appropriate master/slave roles and address parameters in software.

Usage recommendations

For reliable operation, keep RS485 wiring short or use proper twisted-pair cable and terminate the line with the recommended 120 Ω resistor at each end of the bus when deploying longer runs. Avoid running RS485 wiring in parallel with high-voltage power lines to reduce interference. Verify signal polarity if communication fails and ensure host serial settings match the connected RS485 devices.
