Available with a lead time
Expect dispatch between Apr 28 and May 01
Introduction
RainbowLink is an advanced USB protocol converter designed for efficient multi-channel serial communication and power output, tailored for IoT and industrial applications. Featuring 4 independent channels—RS485, RS232, and 2 TTL channels—RainbowLink serves as an all-in-one solution for engineers managing multiple communication protocols in IoT ecosystems. The device supports Windows and Linux operating systems, and it is compatible with devices like LattePanda and Raspberry Pi. RainbowLink is driver-free for most setups; however, installing the optional drivers enhances functionality by assigning unique device identifiers, making it even easier to manage.
With simultaneous 12V, 5V, and 3.3V power outputs, RainbowLink 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
RainbowLink 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
RainbowLink 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, RainbowLink 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 RainbowLink, external power supplies are no longer necessary, allowing for quick and convenient sensor testing even in remote or outdoor environments.
