MOSFET is an electronic devices with good switching characteristics. It is widely used in circuits, such as power supplies switching ,motor drives, lighting dimmer and so on. Relay is another kind of module with switching characteristics. Since relay works relying on mechanical contacts to open or shut. In this way it s will inevitably lead to relay's stopping working while switching time is too short. And papa sound made by relay in some situations is annoying.
We designed a 4-channel MOSFET switch. It can supply up to four groups of electronic switches to control different circuit blocks respectively. Limited by the working priciples, MOSFET can only be used to control the DC circuit, such as DC-LED screen and so on, but not suitable for AC circuit control.
In some extreme cases,It can be used to control 100V/33A DC circuit. However, it is suggested that the controlled DC voltage is more than 9V.

Never hunt around for another crystal again, with the Si5351A clock generator breakout This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz up to 150 MHz.
 
The Si5351A clock generator is an I2C controller clock generator. It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions. By setting up the PLL and dividers you can create precise and arbitrary frequencies. There are three independent outputs, and each one can have a different frequency. Outputs are 3Vpp, either through a breadboard-friendly header or, for RF work, an optional SMA connector.
 
We put this handy little chip onto it's own breakout board PCB, with a 3.3V LDO regulator so it can be powered from 3-5VDC. We also put level shifting circuitry on the I2C lines so you can use this chip safely with 3V or 5V logic.

The louder the sound, the more the LED lights up from the bottom up. With the ups and downs of the sound, the LED will also jump with the music, especially when the DJ is playing.
The independent comparator circuit is a little more complicated, but its structure and principle are easier to understand.
With anti-reverse connection protection diode, effectively prevent power polarity reverse connection caused by burning circuit, more suitable for DIY.
About the signal input: the board comes with a microphone, do not need to connect the audio signal, can induction receive external sound source control LED light bead flashing, the disadvantage is that the sensitivity is not as good as the line input, easy to be affected by other external sound.
If you need line input, this step is talking about audio signal (such as mobile phone or computer headphone hole is, can not be connected to the output of the power put or on the horn), you can take out the microphone, the signal is directly introduced from the microphone, if the lamp is all bright, then adjust potentiometer (reduce the counter clock) recommend this kind of connection.
