I will design rfid nfc pcb, access control, smart card system, stm32 rfid and esp32
About this Gig
Are you building an RFID or NFC-based access control system or smart card solution for your project, product, or prototype? Youre in the right place.
I provide embedded hardware support for RFID/NFC systems, access control devices, and smart card reader solutions using STM32 and ESP32 platforms. These systems are widely used in security applications, attendance tracking, door access systems, and smart identification solutions.
What This Service Covers
- RFID/NFC reader integration (RC522, PN532, etc.)
- Smart card system development
- STM32 and ESP32 microcontroller integration
- Access control system hardware
- Relay and electronic lock control interface
- Buzzer and LED indicators
- Communication interfaces (UART, SPI, I2C)
Why Choose Me
- Strong experience in embedded systems and microcontroller based hardware
- Practical knowledge of STM32 and ESP32 integration
- Understanding of RFID/NFC communication protocols and modules
- Focus on stable, real world working hardwarenot just theoretical design
If you need a reliable RFID/NFC access control or smart card solution using STM32 or ESP32, feel free to reach out. I will help you turn your idea into a functional embedded hardware system.
FAQ
What types of RFID/NFC systems do you support?
I support RFID and NFC-based systems such as access control, smart card readers, attendance systems, and identity verification devices using common modules like RC522 and PN532.
Can you integrate STM32 and ESP32 in the system?
Yes. I work with both STM32 and ESP32 microcontrollers depending on performance, connectivity, and project requirements.
Can this be used for door access control systems?
Yes. The system can be used for door locks, relay-based access control, and smart entry systems with RFID/NFC authentication.
What hardware components can be included?
Typical components include RFID/NFC modules, microcontrollers, relays, buzzers, LEDs, power regulation circuits, and communication interfaces like UART, SPI, or I2C.
Will I receive manufacturing files?
Yes. You will receive: Schematic files PCB layout files Gerber files Bill of Materials (BOM) Pick & Place files (if needed)
Can you build IoT-enabled access control systems?
Yes. IoT features such as Wi-Fi or Bluetooth (mainly using ESP32) can be integrated depending on your project needs
Can you improve or modify an existing design?
Yes. I can review, optimize, or upgrade your existing RFID/NFC or access control hardware design
