USB-UART-PROG is a compact and reliable USB to UART programming interface designed for developers, makers, and hobbyists working with microcontrollers, embedded systems, and serial-based communication devices. Whether you're debugging firmware, flashing a new bootloader, or simply establishing a serial communication channel between your computer and a target device, USB-UART-PROG provides a seamless and efficient solution.

This project was created to offer a plug-and-play USB to UART bridge that is easy to use, flexible in voltage compatibility, and robust enough for both prototyping and long-term deployment. It supports common UART signal levels (typically 3.3V and 5V), making it ideal for interfacing with a wide variety of platforms, including Arduino, ESP32, STM32, Raspberry Pi (via GPIO UART), and many others.

The USB-UART-PROG uses a well-supported USB-to-serial chip to ensure broad driver compatibility across operating systems including Windows, macOS, and Linux. Once connected, the device shows up as a standard COM port or tty device, and can be used with virtually any terminal software or programming tool.

Designed with simplicity and reliability in mind, USB-UART-PROG includes onboard signal LEDs for TX and RX activity, reverse-polarity protection, and optionally, jumper-selectable voltage levels to suit your target hardware. The compact PCB layout makes it easy to integrate into any workspace, whether on a breadboard, test rig, or permanent setup.

Open-source by nature, USB-UART-PROG includes schematics, PCB files, firmware (if applicable), and full documentation to support modification, replication, or further development. Contributions from the community are welcome, and the project aims to remain a helpful and accessible tool for serial communication tasks of all kinds.

If you're looking for a dependable, simple, and open USB-to-serial converter that "just works", USB-UART-PROG is the tool for the job.
