HydraNFC Shield v2 is shield for HydraBus v1 and it is based on STMicroelectronics ST25R3916 NFC chipset which is today the most powerful and versatile NFC chipset available on the market.

HydraNFC Shield v2 shall be plugged on top of HydraBus v1 with a dedicated open source firmware (but it can also be used with any other MCU).

HydraNFC Shield v2 is for anyone interested in Learning/Developping/Debugging/Hacking/Penetration Testing for basic or advanced NFC communications.

Summary of HydraNFC Shield v2 hardware features:

• NFC Reader/writer, NFC Card emulation, NFC Active and passive peer to peer
• Support NFC-A / ISO14443A up to 848 kbit/s, NFC-B / ISO14443B up to 848 kbit/s, NFC-F / FeliCa up to 424 kbit/s, NFC-V / ISO15693 up to 53 kb/s, NFC-A / ISO14443A and NFC-F / FeliCa card emulation
• 1.6W output power at 5V with Differential Antenna and Variable capacitors for NFC Automatic antenna tuning (AAT)
• Low level mode to implement MIFARE Classic compliant or other custom protocols, Automatic gain control and squelch feature to maximize SNR
• Measurement of antenna voltage amplitude and phase, RSSI, on-chip supply and regulated voltages

This firmware is fully open source and based on HydraFW and is specific to HydraBus v1 with HydraNFC Shield v2 it use STMicroelectronics RFAL for ST25R3916
