I will design custom pcb layout for rs485, rs232, usb, i2c,ttl, and protocol convert

Are you looking for an expert Hardware & PCB Design Engineer to create a reliable serial communication or protocol conversion board?

I specialize in designing production-ready Printed Circuit Boards (PCBs) for industrial and commercial applications, ensuring high noise immunity, signal integrity, and robust ESD protection.

Supported Interfaces & Conversions:

• Serial Interfaces: RS485, RS232, RS422, UART / TTL (3.3V & 5V)
• USB Interfaces: USB to TTL (CH340, FT232, CP2102), USB to RS485/RS232
• Custom Converters: Isolated RS485 to RS232, Modbus hubs, Multi-port transceivers
• Power Management: Onboard buck/boost regulators, USB power delivery, industrial 12V/24V inputs

What You Will Get in the Final Output:

• Schematic files (EasyEDA, Altium, KiCAD, or Eagle)
• PCB Layout Gerber & Drill files (Ready for PCBWay, JLCPCB, etc.)
• Bill of Materials (BOM) with LCSC/Mouser part numbers
• 3D STEP file for enclosure design
• Centroid/Pick-and-Place file for automated SMT assembly

Why Choose My Service?

• Integrated ESD protection, TVS diodes, and optocoupler isolation for harsh environments.
• Optimized trace impedance and grounding for noise-free high-speed communications.
• 100% DFM (Design for Manufacturing)
