The circuit diagram is as follows:
In addition: 5,6 feet are used in battery-powered applications, the touch-sensing power supply is DC3.3V-5V, the current is about 5uA, it must be always powered, and when there is a finger, the sensor outputs a high level, wake-up the microcontroller to the fingerprint module. Electricity, so as to achieve the purpose of power saving.

1. The price does not include tax, please do not bargain for a small amount of purchase. More than 10 sets of prices are negotiable.
2. Packaging: Industrial packaging for parts
3. Because this product is a component, you need to have a certain professional foundation during development, and do not provide basic technical support; there are quality problems that can be exchanged and cannot be returned. For the application of this product on a large scale, technical support is provided directly by the manufacturer. .
4. Since the fingerprint module is a component, its interface has no protection circuit. Don't make mistakes when wiring and power supply. Otherwise, burning the main chip is not guaranteed. Pay special attention to student friends.
5. The surface of the acquisition chip is scratched, and the traces and wear are not guaranteed. Please do not scratch or hit the hard object when using it.
6. I am unable to provide teaching services because I don't know the technology. Students and friends should be careful to purchase. Please contact the buyers who have high requirements for service.
