NRF24L01 Transceiver Module Let's take a closer look at the NRF24L01 transceiver module. It uses the 2.4 GHz band and it can operate with baud rates from 250 kbps up to 2 Mbps. If used in open space and with lower baud rate its range can reach up to 100 meters. The module can use 125 different channels which gives a possibility to have a network of 125 independently. The Arduino nano to nRF24L01 pin connection is as follows (note that you may need to connect it differently if you use a different arduino board, refer to the RadioHead library): VCC - 3.3V; GND - GND; CE - D8; CSN - D10; SCK - D13; MOSI - D11; MISO - D12; IRQ - Not connected; Further, I use D5 for the button, D4 for the red LED and D3 for the green one, each connected with a 220 Ohm resistor. It gets a lot easier with Arduino since the libraries are readily available. The module has on operating voltage from 1.9V to 3.6V (typically 3.3V) and consumes very less current of only 12mA during normal operation which makes it battery efficient and hence can even run on coin cells. Even though the operating voltage is 3.3V most of the pins are 5V tolerant and hence can be directly.
