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 don't know the technology, I can't provide thoughtful technical support. Student friends should be careful to buy, and buyers who have high requirements for service should bypass.
