## Description

A multi-protocol converter board that supports USB, TTL, RS232, and RS485 interfaces. It can convert signals between any two protocols and supports one input to multiple outputs simultaneously — for example, converting a USB signal to TTL, RS232, and RS485 at the same time. Based on the FTDI FT232R chip, the board provides reliable serial communication between controllers, computers, and industrial devices. It operates at 3.3V to 5V and includes a power indicator LED. Note: The board is divided into A and B interface groups. Signals can be converted between A and B groups. Signals within the same group cannot be converted — only one sender per group is allowed, but multiple receivers are supported. Key Features Multi-Protocol Support – USB, TTL, RS232, and RS485 conversion One-to-Many Output – Single input can drive multiple output protocols simultaneously FT232R Chip – Reliable FTDI USB-to-serial conversion Dual Voltage – 3.3V to 5V operating range Power LED – Onboard power indicator Specifications Supply Voltage – 3.3V to 5V USB Chip – FTDI FT232R Protocols – USB, TTL, RS232, RS485 Dimensions – 52 × 37 mm Ideal For Serial communication between different protocol devices Industrial equipment interfacing Multi-protocol debugging and development Controller-to-controller communication bridges Package Contents 1× Multi USB/RS232/RS485/TTL Converter Resources Wiki documentation Schematic (PDF) FT232R datasheet (PDF) FTDI VCP driver download
