DFROBOT RainbowLink 4 Channel USB to Serial Converter (RS485 / RS232 / TTL)

With simultaneous 12V, 5V, and 3.3V power outputs, Rainbow Link eliminates the need for multiple converters and external power supplies, making it ideal for testing and development across diverse industrial, agricultural, and laboratory environments.

Quick-Connect Lever Terminals for Easy Wiring

Rainbow Link features lever-type quick-connect terminals, allowing for rapid, reliable wiring without the need for tools or connectors. This innovative design supports over 2000 connect-disconnect cycles and fits both pin headers and sockets, ensuring maximum flexibility. The result is a clean, organized setup that reduces preparation time and minimizes the risk of loose connections, essential for reliable test environments.

4 Independent Channels in 1 Device

Rainbow Link combines four isolated communication channels—1×RS485, 1×RS232, and 2×TTL—within a single device. This setup allows engineers to replace multiple converters, streamlining configurations and reducing clutter on workstations. Each channel operates independently, enabling simultaneous monitoring and control of multiple serial devices, greatly simplifying complex multi-protocol setups.

Flexible Power Output Options

Supporting a range of testing needs, Rainbow Link provides three voltage outputs: 12V (800mA), 5V (2A), and 3.3V (200mA). This versatile power solution ensures compatibility with various sensors and devices, especially in field testing where power sources are limited. With Rainbow Link, external power supplies are no longer necessary, allowing for quick and convenient sensor testing even in remote or outdoor environments.
