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.
