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 →Is your RaspberryPi overheating? Whether it’s in a hot environment or your RPi is crunching non-stop we have a solution – the Raspberry Pi Ultimate Cooling Dual Fan!
This heatsink is high-speed yet low noise and includes a heat sink. 3M thermal tape is included to help ensure the efficient and swift cooling of the processor. We tested this heatsink on the Raspberry Pi ourselves, and it passed our test! It’s ideal for your Raspberry Pi 4 as it was designed to be compatible with the most popular cases. We know this will bring you a fantastic user experience!
Note: Please put the heat sink (with adhesive paper) to the position shown above. Be sure to leave room for the GPIO, and keep the heat sink away from the capacitor.
