            TEL0185 RainbowLink 4-Channel USB to Serial Converter
                    The DFRobot TEL0185 RainbowLink 4-channel USB to serial converter integrates RS485, RS232, and TTL channels and has multi-voltage output and multiple platform compatibility
    

The DFRobot RainbowLink is an advanced USB protocol converter specifically designed to achieve efficient multi-channel serial communication and power output. It is suitable for scenarios such as IoT (Internet of Things), industrial embedded development, and debugging. RainbowLink has four independent channels: RS485, RS232, and 2 TTL. This device supports Windows and Linux operating systems and is compatible with devices such as LattePanda and Raspberry Pi. In most cases, RainbowLink does not require the installation of drivers; however, installing the optional drivers can enhance its functionality by assigning unique device identifiers, making it more convenient to manage. RainbowLink can simultaneously output 12 V, 5 V, and 3.3 V power, eliminating the need for multiple converters and external power supplies. This makes it highly suitable for testing and development work in various industrial, agricultural, and laboratory environments.
