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 →Raspberry Pi Compute module 3+ from Circuitrocks is ideal for DIY electronics builds.
Great for Arduino, ESP32, Raspberry Pi, and robotics or school projects here in the Philippines.
The Raspberry Pi Compute Module 3+ (CM3+) is designed for industrial and embedded applications, offering the same powerful computing performance of the Raspberry Pi 3 Model B+ in a more flexible form factor. With a standard SODIMM connector, the CM3+ allows developers to integrate Raspberry Pi functionality into custom hardware designs, making it ideal for prototyping, scaling, and mass production.
The CM3+ is powered by a Broadcom BCM2837B0 quad-core processor running at 1.2GHz, paired with 1GB of LPDDR2 SDRAM. Storage options vary depending on the model, with eMMC flash memory or a “Lite” version that allows external storage via the user’s design.
