HydraNFC 1.0 Specifications

The HydraNFC is an NFC shield hardware (to be plugged on top of HydraBus) to sniff/read/write/emulate any 13.56MHz NFC tags for anyone interested in advanced NFC Research/Dev/Debug/Hack/PenTest on NFC products.
It has been designed to be used with HydraBus but can also be used with other MCU.

The HydraNFC is less expensive, more powerful/extensible than Proxmark3 Hardware and does not requires an FPGA (all is done by the MCU Cortex M4F@168MHz with the help of HydraBus with ultra fast unique algorithm to sniff & decode in real-time PICC/PCD NFC cards).
