FAQs:
Q1: Can I connect this module directly to Arduino 5V pins?
A: ❌ No, it requires 3.3V. Use a 3.3V regulator and logic level shifter if needed.

Q2: What is the difference between NRF24L01 and NRF24L01+PA+LNA?
A: The PA+LNA version offers longer range and stronger signal due to the amplifier and antenna.

Q3: How far can it transmit data?
A: Up to 1 kilometer in open areas (line of sight).

Q4: Which library should I use with Arduino?
A: Use the RF24 library available in the Arduino IDE.
