About this Gig
I design professional RFID and NFC PCB hardware for access control smart locks card readers authentication devices asset tracking attendance systems and connected products. I can develop LF and HF contactless hardware and support UHF RFID applications where the required reader architecture and RF front end are appropriate.
My work covers RFID reader PCB NFC reader hardware antenna integration matching networks RF layout grounding component placement power management and MCU connectivity. I can integrate controllers such as ESP32 and STM32 with interfaces including SPI I2C UART USB RS485 and Wiegand for access control and embedded systems.
A major focus is real world RF performance. I consider antenna placement read range detuning enclosure effects interference grounding and manufacturability rather than treating the PCB as a simple routing task. Existing designs can also be reviewed for antenna problems communication instability and layout improvements.
Depending on the project I can provide schematic PCB layout BOM Gerber drill Pick and Place source files and manufacturing documentation suitable for prototype or production workflows.
FAQ
Can you design a custom RFID or NFC reader PCB?
Yes. I can design RFID and NFC reader hardware including schematic, PCB layout, antenna integration, matching networks, component selection and manufacturing files.
Can you design the RFID or NFC antenna?
Yes. I can integrate or design the appropriate antenna and account for placement, matching, grounding, PCB geometry and enclosure constraints.
Can you improve RFID read range?
Yes. I can review antenna placement, matching, grounding, RF layout, interference and enclosure effects to identify potential causes of poor read performance.
Do you support access control systems?
Yes. I can design PCB hardware for smart locks, badge readers, door access, authentication devices, attendance systems and related embedded products.
Do you support ESP32 and STM32?
Yes. RFID and NFC reader hardware can be integrated with ESP32, STM32 and other microcontrollers using SPI, I2C, UART, USB or other required interfaces.
Can you design UHF RFID hardware?
Yes. I can work with UHF RFID reader architectures, RF front ends and antenna requirements depending on the target frequency, reader IC and application.
Can you work with an existing RFID PCB?
Yes. I can review an existing schematic or PCB for RF layout, antenna integration, component placement, grounding, manufacturability and potential performance issues.
What manufacturing files will I receive?
Depending on the package, deliverables can include editable PCB source files, schematic, BOM, Gerber, drill, Pick and Place and relevant manufacturing documentation.
Can you design RFID hardware around my enclosure?
Yes. Mechanical constraints, antenna clearance, battery position, metal components and enclosure materials can be considered during the PCB and antenna design process.
What information do you need before starting?
Ideally provide the RFID or NFC technology, target frequency, desired read range, antenna constraints, PCB dimensions, power source, enclosure information, reader IC or module and required communication interface.
