New eagle project:
A PN532 chip with the resonnant circuit (a friend working on a more suitable antenna for the NFC ring). Connexion by SPI.
******link for the pn532 ******
this is for a project of a radio frequency switch with nfc control.. I have not yet the implenter technology for the PN532 (0.2mm space between pins). So I'll see if the mechanical engraver can achieve the board or if I should use a QFN32 adapter -> DIP 32
I also working on a simular project using a chip TRF but it is related to my job and I can not disseminate plans ... sorry!
