Hi There, I am a senior Ph.D. Level Expert and Have more than 5 years of experience in electronics and embedded design. I have experience with PN532 Smart reader. Just check my profile and share your details. Time and Budget will be discussed. Thanks

I have PN5322 and did a project on it its a smart bracelet, I can help you in this task. I can show you my work for your reference.

Hi, based on datasheet of the module, the I2C address cannot be changed. So there are two options to use two devices 1: Use two different I2C busses, one for each PN532 module 2: Use a I2C multiplexer so that same I2C bus can be used for both devices
