The nRF54LM20 DK supports an NFC tag.
NFC-A Listen Mode operation is supported on the nRF54LM20B SoC. The NFC antenna input is available on connector J5 on the nRF54LM20 DK.
Figure 1. NFC antenna connector
NFC connects to the antenna using two pins, NFC1 and NFC2, which are shared with GPIOs P1.01 and P1.02. These pins are by default configured to use the NFC antenna.
Configuring NFC pins as GPIOs
To use pins P1.01 (NFC1) and P1.02
(NFC2) as GPIOs, move the 0 Ω 0402 resistors from R33 and
R34 to R3 and R4. Disable the NFC peripheral by adding
&uicr { nfct-pins-as-gpios; }; to your board devicetree files. See
Configuring and building for instructions.
