Hi all,
Can anyone assist me in identify the tuning / resonant capacitors on my Proxmark3 Easy board, see image below. Much appreciated!
I'm guessing that I also need to sort out that solder short that I highlighted, haha.
Cheers,

Hello,
eventually i can help you... because i had answered me some of the questions before.
1. Solder bridge between Pin 28 and 29 is correct,as this Pins have a GND connections.
2. tuning caps - the caps to tune external antenna to resonance in the RLC design should be the caps in the circle of the attached picture.
The yellow circle is for 13,56 , the othe for LF section
Last nigth i try to find out what developer of Proxmark Easy have done to find out if it eventually can be improved.
I was'nt able to find a schematic of the Proxmark 3 Easy design, thats why i createdesign files by analysis of HW.
At this time i have not completed the analysis but i create some Eagle design files ( with not correct values - not finished yet..). If someone is interested and if it is allowed i can publish the data.
Best Regards,
Frank
same guy who did rdv1, rdv2, rdv3 easy, rdv4.... Not sure you will improve much of his designs, its not like there is a ton of crappy clones of rdv3 easy out there. If you got one of them, then you most likely can improve the components. If you got a geniune rdv3 easy you don't.
With that, the latest iteration is the rvd4. Feel free to improve that one instead.
