Origin
Nano With 2.4G compatible for arduino Nano 3.0 CH340 USB driver ATMEGA328P NRF24L01
Properties
If the NRF24L01 is really a version without "+", then it does not support 250kb/s, which is the default for MySensors. Extract van MySensors/MyConfig.h:
/** * @def MY_RF24_DATARATE * @brief RF24 data rate. * * - RF24_250KBPS for 250kbs * - RF24_1MBPS for 1Mbps * - RF24_2MBPS for 2Mbps. * * @note nRF24L01, BK2401, BK2421, BK2491 and XN297 does not support RF24_250KBPS * @note BK2401 does not support RF24_2MBPS */ #ifndef MY_RF24_DATARATE #define MY_RF24_DATARATE (RF24_250KBPS) #endif

- D7 - CE, D8 - CSN, D11 - MOSI, D12 - MISO, D13 - SCK
- Arduino Nano, ATmega 328p (Old Bootloader) CE pin D7, CSN pin D8
| nRF24L01 Pins | Arduino Pins |
|---|---|
| CE | D7 |
| CSN | D8 |
| SCK | D13 (as expected) |
| MOSI | D11 (as expected) |
| MISO | D12 (as expected) |
| IRQ | NC (I think) |
