Diagrama de pines
Pines de Radio NRF24L01 de 2.4GHz (cabezal 2×4)
Pines
- 1 GND (square pad corner)
- 2 VCC (3.3V ONLY — 5V kills it; logic pins are 5V tolerant)
- 3 CE (radio enable)
- 4 CSN (SPI chip select)
- 5 SCK
- 6 MOSI
- 7 MISO
- 8 IRQ (optional interrupt)
- A 10–100µF capacitor across GND/VCC fixes most instability
