Keyestudio PN532 NFC/RFID Controller Shield for arduino uno r3

The Keyestudio PN532 NFC/RFID Controller Shield is a versatile expansion board designed to bring near-field communication to your Arduino Uno R3 projects. It is ideal for students, makers, and educators looking to build contactless access control systems or data exchange devices.

Integrated antenna and easy stacking

This shield features an onboard antenna, eliminating the need for an external antenna coil and keeping your projects compact. It is designed to stack directly onto your Arduino Uno R3 control board for a neat, solder-free setup.

Flexible interface communication options

The shield supports SPI, IIC, and UART interfaces, allowing you to easily switch between communication protocols to suit your project's requirements. This flexibility simplifies integration with various microcontroller setups.

Reliable near-field communication

Powered by the NXP PN532 chip, this module operates at 13.56MHz and is fully compatible with ISO14443 Type A and B standards. It provides a reliable communication distance of up to 2.4 cm for contactless data exchange.

Efficient power consumption profiles

Operating at a working voltage of 3.3V with a power supply range of 3.3V to 5.5V, the shield draws a maximum of 150mA. It features an onboard PWR indicator and consumes just 100mA in standby mode and 120mA during active read or write operations.

Compact and lightweight design

Measuring just 69mm by 54mm by 24mm and weighing only 18.3g, this shield adds minimal bulk to your Arduino setup. It is perfect for integration into small enclosures and portable prototyping projects.
