The USB to TTL Converter is a compact and versatile tool designed around the **FTDI FT231XQ-R** chipset. It provides reliable USB to serial UART communication for embedded systems, microcontrollers, and development boards. With support for **both 3.3V and 5V logic levels**, activity indicator LEDs, and JST-GH connectors for easy interfacing, this converter is ideal for prototyping, debugging, and field applications.

This project is **Open Source Hardware**, built for ease of use and wide compatibility.
