Just a news about a new Hardware PCB i have designed with Eagle, it is an NFC Breakout board using latest Texas Instrument NFC chipset the TRF7970A and including 13.56MHz antenna with an option to connect an external SMA NFC antenna (SMA-142-0701-801/806) .
It is also compatible with Input Voltage from 2.VDC7 to 5.5VDC and I/O Voltage level programmable from 1.8VDC to 5.5VDC.
It supports Near Field Communication (NFC) Standards NFCIP-1 (ISO/IEC 18092), NFCIP-2 (ISO/IEC 21481) and protocol ISO15693, ISO18000-3, ISO14443A/B, and FeliCa.
Advantage against PN532 chipset/breakout board are:
- TRF7970A is cheaper and available.
- Documentations including datasheet are public/full and available directly without any registration or NDA.
- Support Direct Mode 0 "Raw RF Sub-CarrierData Stream" to encode/decode all 13.56MHz subcarrier data stream.
