The board should be powered by battery (two or three dry batteries or a single lithium battery 18650), followed by a linear power supply. If you must use a switching power supply, please add a filter circuit to ensure that the circuit power supply ripple is small, ripple The louder the noise, the bigger it will be.





Board parameters:





1>.power: DC 3-7V (generally recommended 3-6V)
