Frequently Asked Questions
Q: Is the PN532 NFC module compatible with both Arduino and Raspberry Pi?
A: Yes! The PN532 NFC module supports SPI, I²C, and UART communication interfaces, making it fully compatible with Arduino boards (Uno, Mega, Nano, etc.) and Raspberry Pi single-board computers. Popular libraries such as Adafruit's PN532 library for Arduino and libnfc for Linux/Raspberry Pi are widely available to get you started quickly.
Q: What types of NFC tags and cards does this module support?
A: The PN532 operates at the standard 13.56 MHz NFC/RFID frequency and supports a wide range of card standards including MIFARE Classic, MIFARE Ultralight, NTAG series tags, ISO14443A/B, and FeliCa cards, among others. This makes it highly versatile for most NFC applications.
Q: What voltage does the PN532 NFC module require?
A: The module supports a supply voltage range of 3.3V to 5V, so it works seamlessly with both 3.3V systems (like Raspberry Pi) and 5V systems (like many Arduino boards) without requiring additional level shifters in most configurations.
Q: Can I use this module for contactless payment or access card emulation?
A: The PN532 supports card emulation mode, which allows it to mimic NFC cards for certain applications. However, for legally compliant payment system use, additional certification and software infrastructure are required. It is most commonly used for access control, tag reading/writing, and peer-to-peer NFC data exchange in maker and prototyping projects.
