√ 3.3V regulator onboard
= 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
- SCK=52, MOSI=51, 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
