DF Robot RainbowLink V2 Isolated USB Protocol Converter – 4 Channel
The DFRobot RainbowLink V2 is a compact, all-in-one USB protocol converter designed for engineers, developers, and technicians working with multiple communication standards. Combining four independent channels—isolated RS485, isolated RS232, and dual TTL (UART)—into a single device, it eliminates the need for multiple adapters while enabling simultaneous communication across different interfaces. With a simple USB Type-C connection, it transforms your laptop into a powerful portable debugging workstation for industrial, IoT, and embedded applications.
Beyond communication, the RainbowLink V2 features an integrated power supply that converts USB input into multiple output voltages (12V, 5V, and 3.3V), allowing you to power and test external devices directly without additional equipment. Full signal and power isolation on the RS485 and RS232 channels protects your system from voltage spikes, noise, and ground loops, ensuring safe operation in demanding environments. With tool-free wiring terminals and smart port identification, this device offers a fast, reliable, and user-friendly solution for field diagnostics and development work.
