How to wire to have access to ISO interface?

I have connected VCC of reader to Vcc_ISO
I have connected RST of reader to ISO_RST
I have connected CLK of reader to ISO_IO_CLK
I have connected GNDof reader to GND
I have connected IO of reader to ISO_IO / CMD

I have used a PCB adapter with ISO interface.

However the “card” is not detected when inserted.

Any idea?

Best regards,
Damien

Hi Damien,

Try connecting Vcc (pin 11 on breakout board) as well as Vcc_ISO. That works for me. I do also have all the GND pins connected to GND.

Regards,
Chris.

Thank you Chris. I have connected as you suggest the Vcc (PIN 11) and one GND (PIN 32) and it was working.

Great.
