How to Wire the GT-511C3 Fingerprint Scanner

The article on the GT-511C3 fingerprint scanner hardware, wiring and connector numbering shows how to connect the fingerprint scanner module to 5V and 3.3V microcontrollers using the Arduino Uno and Arduino Due as examples.

The article includes the pin numbers and functions as well as voltage levels and default baud rate. Information is provided that shows how to make up a cable with connector that will plug into the GT-511C3 FPS (fingerprint scanner).

Raspberry PI Laptop Computer

The Raspberry PI laptop computer reported in Elektor News was created using a 3D printer for the case, model B+ Raspberry PI, laptop keyboard, track-pad, WiFi, battery and 13.3″ HD screen. The battery lasts 6 to 8 hours.

The name for this laptop is “PI-TOP”, you can read more about it on the Pi-Top website and also follow the project on Facebook for updates.
