The arduino uno board can supply 5v or 3.3v power. In this arduino tutorial we will learn how to use the nrf24l01 rf transceiver module to make a wireless communication between two arduino boards. In this experiment 5v is adopted, so the minimum resistance of the current limiting resistor should be (5 v to 1.8 v)/20 = 160 ohm.
The power consumption of this module is just around 12ma during transmission, which is even lower than a single led.
