This is a simplified build of goebish's nRF24 multi-protocol RC transmitter for OpenTX enabled transmitters with external RF support such as the FrSky Taranis.
The Arduino Nano provides a 3.3v which makes it an ideal choice with the nRF24 module. However the nRF24L01 is 5v tolerant, it is preferable to use 3.3v from the Arduino to power it.
| Arduino | nRF24L01 | Transmitter |
|---|---|---|
| 3.3v | VCC | |
| GND | GND | GND |
| VIN | vOUT | |
| D2 | PPM | |
| D3 | MOSI | |
| D4 | SCK | |
| D5 | CE | |
| A0 | MISO | |
| A1 | CSN |
