Coil (transmit frequency
）
Working principle description: Supply power to the USB input,
step down all the way to 5V through the LDO 7150 to supply power
to the MCU master control, and the other to supply power to the MOS tube.
the MOS tube, and the MOS tube drives the transmitting coil.
After the main control is powered on,
it outputs a PWM drive signal to drive
110-205KHz
