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 →These connectors allow for convenient wiring between your Lipo batteries and ESCs (or Power supply circuit) in any of your RC applications. The XT90 in particular can draw exceptionally high currents compared to his XT60 and XT30 counterparts. The design of the XT connector series ensures reverse polarity protection and thanks to its nylon material, you needn’t worry about overheating during soldering. This connector is a great pick for circuits that draw 90A of continuous current.
