The schematic diagram of the circuit is as follows: the interface is MX1.0-6P
In addition: Pins 5 and 6 are used in battery-powered applications. The touch sensing power supply is DC 3.3V-5V, and the current is about 5uA. It must be powered normally. When there is a finger, the sensor outputs a low level to wake up the microcontroller and send it to the fingerprint module. electricity, so as to achieve the purpose of saving electricity.
