Note:
The board should use battery power as much as possible (two or more dry batteries or lithium batteries such as 18650), or use a linear power supply. If a switching power supply is used, please add a filter circuit to ensure that the circuit power supply ripple is small. The larger the ripple, the larger the noise.
