| ====== nRF24 multi-protocol RC transmitter ====== | ====== nRF24 multi-protocol RC transmitter ====== | ||
| + | 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. | ||
| ===== Parts ===== | ===== Parts ===== | ||
| + | * 1x Ardunio Nano rev3.0 | ||
| + | * 1x nRF24L01 transceiver module | ||
| + | * 1x 4cm x 6cm PCB prototype board | ||
| + | * 1x 2.54mm female connector header row //(optional)// | ||
| + | * 26 AWG wire | ||
| ===== Steps ===== | ===== Steps ===== | ||
| + | - Upload the [[https://github.com/goebish/nrf24_multipro/archive/master.zip|nrf24_multipro]] sketch to the Arduino Nano. | ||
| + | - Layout the Arduino Nano on the PCB prototype board (e.g. top most left). | ||
| + | - Layout the nRF24L01 transceiver module on the PCB prototype board (e.g. top most right of Arduino Nano). | ||
| + | - Wire up the pins for the transmitter. | ||
| + | - Wire **GND** from both Arduino and nRF24L01 to **GND** pin of transmitter. | ||
| + | - Wire **VIN** from Arduino to **+BAT** pin of transmitter. | ||
| + | - Wire **D2** from Arduino to **PPM** pin of transmitter. | ||
| + | - Wire the pins from the Arduino to the nRF24L01 transceiver module. | ||
| + | - Wire **3.3V** from Arduino to nRF24L01 **VCC** pin. | ||
| + | - Wire **D3** from Arduino to nRF24L01 **MOSI** pin. | ||
| + | - Wire **D4** from Arduino to nRF24L01 **SCK** pin. | ||
| + | - Wire **D5** from Arduino to nRF24L01 **CE** pin. | ||
| + | - Wire **A0** from Arduino to nRF24L01 **MISO** pin. | ||
| + | - Wire **A1** from Arduino to nRF24L01 **CSN** pin. | ||
| + | |||
| + | //TIP: For connection to the external RF pins on the transmitter, you could use a 4-pin servo cable instead of the 2.54mm pitch female headers.// | ||
