Project Description

The project is a USB to UART converter

This is a complete PCB project that enables serial communication between a computer (USB) and electronic systems and microcontrollers via the UART interface.

The board is intended for development, testing, programming, debugging, and educational and DIY projects, and is a reliable and common solution for connecting a computer to external components.

The project includes a professional design of a printed circuit board, with all the files required for manufacturing, assembly, documentation, and future editing in industrial software.

The package includes everything needed for manufacturing and assembly

• Electrical schematic (PDF, PNG, SVG, JSON) – shows the connections of the USB components, the communication chip, resistors, connectors, and auxiliary components.

• PCB Layout – full physical design of the printed circuit board, including the layout of components and tracks.

• Gerber Files + Pick & Place – standard files for professional manufacturing and automatic assembly.

• BOM (Bill of Materials) – a complete list of components for assembling the board.

• CAD and 3D files (OBJ / DXF) – for documentation, visualization and mechanical design.

• Altium Designer compatibility files (PCBdoc, Schdoc) – for further development and professional editing.
