Compact USB to RS485 converter Joy-IT SBC-ttl-rs485 provides a single USB 2.0 Type-A plug to a 2-wire RS485 connection for use with Raspberry Pi, Arduino and other SBCs or microcontroller setups. Supplied cable length is listed as 0 m and the unit is black. Suitable for industrial serial communication, sensor networks and RS485 device control where a simple USB interface is required.

## Long 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.
