So, you can connect it directly to the 3.3V pin of our Arduino. It is placed inside a square for easy identification. With Automation Code is easy even for beginners 1380 views 0 respects. Now, lets have a look at the pinouts and specifications of the NRF24L01 module: GND: is the Ground Pin. I am going through the steps of coding the wireless communications and am currently running into issues that I cannot figure out browsing the forums here and google in general.Ĭurrently I have the Arduino wired up with a nRF24L01P+PA+LNA RF Wireless Transmission Module, according to the guide. 4WD Rover with Sonar, Mega, RF24, L298N(W/ SELF DRIVE MODE) Using an RF24 to send and receive data to control a 4WD rover with radar. Here are a few of the most important components and connectors to be aware of: Dimensions: The board measures 101.52mm x 53.3mm. There are pin mappings to Atmega8 and Atmega 168/328 as well. The CE and CSN pins are connected to any digital pin of the Arduino. MISO to 12 for Arduino Uno, Nano, and 50 for Arduino Mega. I have been unsuccessful in getting a Mega/RF-Nano or Uno/RF-Nano combination to communicate. The SCK pin should be connected to pin 13 for Arduino Uno, Nano, and 52 for Arduino Mega. The other set is used on a pair RF-Nanos and uses nRF24L01.h with Mirf.h and MirfHardwareSpiDriver.h. The Arduino Mega 2560 Rev3 is a large development board that is packed with a variety of components and features. Below is the pin mapping for the Atmega2560. One set is used on a Mega/Uno combination and uses the RF24 library and nRF24L01.h. The MOSI pin from the nRF24L01 board connects to pin 11 for Arduino Uno, Nano and to 51 for Arduino Mega. Then upload the code below which can be found in your Arduino IDE (after installing the RadioHead library). Follow the circuit above for your client. Important: Input voltage is of 1.9V3.6V, do not exceed this voltage, otherwise it will fry your module. I am undertaking a project where I need to setup a transmitter using an Arduino Uno R3 board, and receiver with a Teensy 3.2 micro controller. Arduino Mega 2560 Rev3 Pin Headers and Components. Pinout Top view of NRF24L01 Client Circuit.
