Challenger RP2040 NFC antenna

Post by David-Reelables »

Quick question, for the Challenger RP2040 NFC board. Is there any way to get a different antenna than the one provided?

Also curious why the design decision to use a ribbon connector vs a ufl connector?

Hi,

Currently we do not have any other NFC antennas but if the requirements are there we have no problems in designing a new one.
What would be an appropriate size for your application ?

Using a flat flex cable connector is a pretty straight forward way of connecting a flexible NFC antenna to a controller. I guess we could have designed it using a solderable U.FL. pigtail but I'm just not that keen on soldering stuff onto flexible PCB's.
