I will design 13 56mhz rfid pcb, nfc reader, antenna nodes, mcu and embedded firmware

Hello and Welcome!

A multi-antenna 13.56 MHz RFID system requires careful coordination between the RF front end, antenna network, reader interface, MCU timing, and firmware state management. Poor antenna isolation, unsuitable matching, noisy power rails, or incorrect switching logic can cause missed reads, false detections, and unreliable antenna identification.

I design custom 13.56 MHz RFID/NFC electronics with the PCB hardware and embedded firmware engineered as one system.

What I Will Provide:

• 13.56 MHz RFID/NFC reader PCB design
• Multi-antenna RFID node architecture
• Antenna switching and control circuits
• RF-aware PCB layout and grounding
• RFID antenna matching and tuning support
• MCU selection and hardware integration
• Power supply and protection circuits
• Antenna selection and switching firmware
• Embedded C/C++ firmware development

Why Choose Me:

1. Hardware and firmware designed as one complete system
2. RF-aware PCB design for 13.56 MHz applications
3. Practical multi-antenna architecture and control
4. Clean MCU and peripheral integration
5. Structured embedded C/C++ firmware
6. Manufacturable PCB layouts and documentation
