Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →In the present time, having a power bank is a necessity, especially if you travel a lot. With this module, you could make your DIY power bank with 2 slots with 5V and 2A output.
This module has a built-in 4 LEDs that show the working state of the batteries and has an automatic shutdown when the battery could not reach the required voltage output. It has a battery protection IC, over-current, overvoltage, and under-voltage protection. It has 2 socket Type A USB. And a small button to activate the front LED flashlight.
It recharges using the micro USB plug with a 5V 2A Adapter.
This module uses a wide range of batteries, like a parallel 18650 batteries (2 to 6 cells), LiPo batteries.
The connection requires only 2 pins, and this module only has B+ for the positive side of the battery and B- for the negative side of the battery.
