RainbowLink is a powerful USB protocol converter built for multi-channel serial communication and power output. With 4 independent channels — RS485, RS232, and two TTL channels, it provides a complete solution for IoT, industrial, and development environments.
It is fully compatible with Windows and Linux systems and supports development platforms like LattePanda and Raspberry Pi. No driver installation required for basic use — just plug and go. Optional drivers enable advanced features like assigning unique device identifiers, ideal for complex configurations.
Key Features

-
3 simultaneous power outputs: 12V, 5V, 3.3V
-
Quick-connect terminals — no tools or soldering required
-
Cross-platform: Supports Windows, Linux, LattePanda, Raspberry Pi
Quick-Connect Lever Terminals
Say goodbye to messy jumper wires and unreliable connections. RainbowLink uses lever-style quick-connect terminals that support over 2000 cycles. They are compatible with pin headers and sockets, making it easy to achieve a clean, fast, and secure wiring setup — perfect for lab and field environments.
4 Independent Channels in One Device
RS485, RS232, and 2×TTL channels operate independently, allowing simultaneous control of multiple devices without interference. Ideal for managing complex communication setups across multiple protocols.
Flexible Power Output Options
No more switching between adapters. RainbowLink provides 3 stable voltage outputs for powering sensors and devices directly:
-
12V (800mA)
-
5V (2A)
-
3.3V (200mA)
This makes it easy to work in remote or mobile setups where traditional power sources may not be available.
