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

Introduction

RainbowLink is a high-performance USB protocol converter designed for multi-channel serial communication and power output, making it ideal for IoT and industrial applications. It integrates four independent communication channels—RS485, RS232, and two TTL channels—into a single device, providing a versatile, all-in-one solution for engineers managing diverse communication protocols.

Compatible with Windows and Linux, as well as devices like LattePanda and Raspberry Pi, RainbowLink is driver-free for most applications, with optional drivers available for enhanced functionality. Additionally, it provides simultaneous 12V, 5V, and 3.3V power outputs, eliminating the need for external power supplies, making it perfect for industrial, agricultural, and laboratory environments.

Key Features

Quick-Connect Lever Terminals for Easy Wiring

RainbowLink features lever-type quick-connect terminals, enabling fast, tool-free wiring. Designed for over 2000 connect-disconnect cycles, these terminals accommodate both pin headers and sockets, ensuring a secure and organized setup while minimizing preparation time and connection errors.

Four Independent Communication Channels

This compact converter includes:

• 1× RS485 channel
• 1× RS232 channel
• 2× TTL channels

Each channel operates independently, allowing engineers to monitor and control multiple serial devices simultaneously, eliminating the need for multiple converters and reducing clutter in complex setups.

Versatile Power Output Options

RainbowLink offers three built-in voltage outputs, providing flexibility for various testing needs:

• 12V (800mA)
• 5V (2A max via Type-C, 500mA via USB-A)
• 3.3V (200mA)

This eliminates the need for external power sources, making it ideal for sensor testing in remote or field environments.
