Topic: HydraBus with HydraNFC, new open source HW for NFC
I have developped a new Open Source hardware HydraBus with HydraNFC (shield for HydraBus) which can read/write/sniff/debug NFC cards with same possibility as proxmark (for NFC 13.56MHz) done with high end MCU (ARM Cortex M4F @168MHz).
The hardware HydraNFC use TI TRF7970A chipset for NFC.
The Hardware and Firmware are planned to be fully open source and soon available on GitHub github.com/bvernoux/hydrabus
You can register your interest on this project here hydrabus.com/?page_id=15
Developers are welcome !! I can even give free boards (production will start soon).
For more details on HydraNFC Shield see hydrabus.com/?page_id=30
This product could support libnfc in future, depending on feedback and interest.
