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 Teensy 4.1 with Headers is a powerful microcontroller board for advanced embedded projects, robotics, audio, lighting, data logging, controls, and connected devices. It uses a fast 600MHz ARM Cortex-M7 processor and comes with pre-soldered male headers, so you can start prototyping faster.
This board gives you strong performance, more I/O pins, Ethernet support, USB host support, a built-in microSD socket, and many communication options. It is a great choice for users who need more speed and flexibility than a standard beginner board.
Note: USB cable, Ethernet connector kit, Ethernet cable, microSD card, sensors, and other accessories are sold separately unless stated in the package.

Teensy 4.1 uses 3.3V logic. Do not connect 5V signals directly to its pins. Using 5V signals may damage the board.
The board can be powered through USB for basic testing. For external power, follow Teensy power guidelines carefully before connecting VIN and USB power.
It is used for fast embedded projects such as robotics, audio, lighting, data logging, controls, sensor systems, and network-connected projects.
Yes. This version includes pre-soldered male headers for easier breadboard use.
Yes. It has a 10/100 Mbit Ethernet PHY, but the Ethernet connector kit is sold separately.
Yes. It can be programmed using Arduino IDE with the Teensy boards add-on.
No. The pins use 3.3V logic and are not 5V tolerant.
