Master (transmitter) example of using nRF24L01 with STM32F407VET6 black boards.
Connect (plug in) the nRF24L01 module to the NRF24L01 connector located on the STM32F407VET6 board as follows:
| nRF24L01 | STM32F407VET6 |
|---|---|
| Vcc | +3.3V |
| GND | GND |
| MOSI | PB_5 (SPI1 MOSI) |
| MISO | PB_4 (SPI1 MISO) |
| SCK | PB_3 (SPI1 SCK) |
| CSN | PB_7 (CS) |
| CE | PB_6 (CE) |
