I'm trying to configure the library to work with my NodeMCU board but I don't understand some things: do I need a level shifter for TX and RX pins? How can I configure HardwareSerial port with it? I'm trying to use the "NMEAdiagnostic.ino" sketch but it can't find my board. My connections:
3V3--->VCC
GND--->GND
RX (GPIO 03)--->TX
TX (GPIO 01)--->RX
Thank you!
