PN532 USB Type-C vs PN532 V4
Both modules are based on the NXP PN532 NFC / RFID controller and support the same tag protocols. The difference is how they connect to the host system: USB versus GPIO (SPI / I2C / UART).
Side-by-Side Comparison
| PN532 USB Type-C | PN532 V4 | |
|---|---|---|
| Host interface | USB Type-C (HID / CDC) | SPI / I2C / UART (switch selectable) |
| Soldering required | No | Yes (pin headers) |
| Power supply | USB bus power | 3.3 V or 5 V GPIO |
| Best host platform | PC, Mac, Raspberry Pi (USB) | Arduino, ESP32, embedded MCU |
| Linux software | libnfc, nfcpy, PCSC | C/C++ library, Python SPI/I2C |
| Supported tag protocols | ISO 14443A/B, MIFARE, NTAG, FeliCa, ISO 18092 | Same as USB variant |
| Antenna | On-board PCB antenna | On-board PCB antenna |
| Typical use case | Desktop NFC reader, kiosk, server-side enrollment | Embedded product, Arduino / ESP32 prototype |
Choose PN532 USB Type-C If…
- Your host is a PC, Mac, or Linux system with USB
- You want plug-and-play without wiring or soldering
- You are using Python (nfcpy), libnfc, or a PCSC-based application
- You are building a kiosk, enrollment station, or access management PC application
Choose PN532 V4 If…
- Your host is an Arduino, ESP32, or other microcontroller
- You need SPI / I2C / UART integration in an embedded design
- You want to build NFC into a product PCB (smaller footprint possible)
- You are using the ELECHOUSE Arduino / ESP32 C++ library
