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 →This breakout board features a USB Micro-B connector with all five pins broken off, making it straightforward but efficient. Excellent for supplying USB 5V power to a project or partnering with a microcontroller that supports USB. A micro-B connector that won't accidentally tear off thanks to through-hole shielding pads for a great, robust connection! One micro B breakout PCB that has been fully made and tested is included, along with a tiny 0.1" header stick that can be soldered on and plugged into a breadboard.
5V Power Supply Module with 5Pin Female Connector for MCU-Micro USB Breadboard B type PCB Converter. For prototype circuits like breadboards, perforated boards, or Vero boards, it is also helpful if all you need is 5V USB power.
Ans. Yes, it uses the VCC pin to supply 5V USB power.
Ans. The answer is that it can transmit electricity via USB, but not for high-current charging.
Ans. Yes, USB OTG via the ID pin is supported.
Ans. It has been tested and constructed completely.
