NRF24 TRANSMITTER schematic


NRF24 TRANSMITTER schematic




This is the final TRANSMITTER scheamtic made with Arduino NANO and the NRF24 module with power amplified antenna and 7 channels to be sent. Make sure the SPI connection is ok. CE and CSN could be any digital pin that you want but CLK must be D13, MOSI must be D11 and MISO must be D12.




Each joystick has 2 potentiometers that will be connected to analog inputs A0 to A3. The toggle switches are digital connected to pins D2 adn d3. Finally the extra potentiometer to A4. Remember to supply 5V and GND to all elements. Add a 3.3 voltage regulator for the NRF24 module. Connect the battery to the sliding switch and the switch to pin Vin and the 3.3V voltage regulator. Add a 10uF cap to the 3.3 voltage.
