there are four LEDs that'll help if you ever need to debug your XBee: RX

A little light soldering will be required to assemble and customize the board by attaching the desired headers but it is a 15 minute task that even a beginner can do the shop so pick up a few while you're here

so this pin can be left disconnected

so thermal issues should be taken into consideration for high currents

Capacitive Fingerprint Sensor / Scanner (UART, 80 Fingerprints) Shipping:2-4 Weeks there are four LEDs that'llThis capacitive fingerprint sensor supports fingerprint capture, image processing, fingerprint storage, fingerprint comparison, and so on. Taking ID809 high performance processor and semiconductor fingerprint sensor as the core, the sensor adopts built in IDfinger6. 0 algorithm, which can complete all fingerprint identification work independently. The product supports UART communication. When working with the Arduino library, it can easily realize
