Important Notes
- Module operates at 3.3V – use level shifters for 5V Arduino
- Use RF24 library by TMRh20 for Arduino
- External antenna required (SMA connector) – included
- Range greatly reduced by walls and obstacles
- Set channel away from WiFi (WiFi uses channels 1, 6, 11)
- Use 10μF capacitor across 3.3V and GND for power stability
