Hi everyone , i created this hacker pcb card,The NFC antenna
(25x48MMNFCANTENNA) is connected to the "LA" pin of the NT3H2111W0FHKH
chip.
The NT3H2111W0FHKH chip is correctly connected with its power and communication pins.
The
LED (LED1) is connected through a resistor (U3, 47Ω) to the "VOUT" pin
of the chip, indicating that it will light up when there is a voltage
output.
The capacitor (C1, 220nF) is connected between "VOUT" and
ground, which is a typical configuration to stabilize the output
voltage. u.easyeda.com/account/user/projects/index/detail?project=04cb6d684d1a4204bc778a9dfacb17c7&listType=all
