Connection Guide
To Arduino Uno/Nano:
- VCC: 5V or 3.3V
- GND: GND
- CE: Pin 9
- CSN: Pin 10
- SCK: Pin 13
- MOSI: Pin 11
- MISO: Pin 12
To Arduino Mega:
- Same but SPI pins differ
- SCK52, MOSI51, MISO=50
Use 5V for onboard regulator, 3.3V for bypass
Cut regulator jumper for external 3.3V use
Do not use 5V directly on NRF module
Ensure regulator can supply 150mA
Troubleshooting
Module not detected:
- Check power supply
- Verify SPI connections
- Avoid loose pins
Wireless not working:
- Check CE and CSN pins
- Verify both modules same channel
- Avoid interference
