    It has possible channels in between 1Mhz spacing so the module can use different channels which makes it possible to have a network of independently working modems in one place. Hi, I managed to create the circuit successfully, but do you know how to amplify the sound coming out of the speaker? Also, it comes with a very powerful audio amplifier in an SMD package which requires very little space. Question 3 years ago. The connection is very simple, a 3.

    With the microphone connected to the circuit the way it is, it will produce an AC current at the base of the transistor based upon the sound wave hitting the microphone.

    It consumes low power and it can communicate with six other nRF24L01 modules at one time when they are in the receiving state.

    forum? Would I have to change the transmission in the serial monitor or would it perhaps be that I have the microphone circuit connected incorrectly?

    If we have to communicate in a company or in a small industry then we use less costly devices like RF communication or walkie-talkie.
