For all ARYGON MCU-equipped the default baudrate is always 9600 baud as this is set by the MCU firmware. If the host bus is USB, the MCU is connected to SiLabs UART-USB bridge.

For devices without MCU the default baudrate of PN532 based products is 115200 baud, for PN531 based it is 9600 baud. If the host bus is USB, a SiLabs UART-USB bridge is directly connected to PN53x chip.


This device is an OEM-only product, that means this device comes without enclosure and is designed to be embedded in the targetted application.

Theses devices are PN532-equipped with a front MCU connected by UART to host.
