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 TPA3118 BTL 60W Mono Digital Amplifier Board delivers up to 60W of single-channel power, making it ideal for subwoofer amplification, PA speakers, and any project that needs to drive one big speaker hard. Based on the TPA3118D2 chip running in bridge-tied-load (BTL) mode for maximum output from a 12–24V supply.
