Illustration:
 The serial port is a TTL level of 3.3V. If you need to connect to the serial port of PC, you need to connect the TTL-USB adapter board before communication.
 The sensor module circuit power supply needs to be powered at all times. Please ensure that the power supply has small ripple and is not interfered by other power supplies.
 If the lock board side performs a power-on and power-off operation for the fingerprint module; it is recommended that the power-off time interval be at least greater than 150ms.
 The master controller should follow the following sequence when controlling the fingerprint module MCU_3.3V to power on; Configure the serial port working mode after MCU_3.3V is powered on. It is not recommended to open the serial port first and then control MCU_3.3V to power on.
 After the main control goes to sleep, RX and TX should be pulled down to avoid excessive power consumption caused by leakage between IO ports.
