Note: Without proper DPC calibration the loading and detuning might exceed the ITVDD
limit, if the symmetrical tuning is used. This might destroy the NFC reader IC
2.2.6.2 PCB for individual antenna matching
Development kit contains 3 PCB boards for individual antenna matching. This boards are
intended for prototyping custom asymmetrical or symmetrical (DPC) antenna design.
Default matching circuit can be replaced by individual antenna matching PCB.
