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 →The XH-M543 TPA3116D2 120W Digital Amplifier Board pushes serious power — up to 2×60W in stereo or a massive 120W mono in bridged BTL mode. Based on the proven TPA3116D2 chip, it's one of the most popular amplifier boards for DIY boomboxes, home theater subwoofers, PA systems, and car audio.
| Module | Power | Supply | Best for |
