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 →A proven Linux single-board computer with a quad-core 64-bit CPU, fast I/O, and dual 4K display output. Pick the RAM you need—2GB, 4GB, or 8GB—and build desktops, dashboards, media centers, robots, and IoT gateways with ease.

Specs summarized for quick selection; check individual batches/revisions for minor differences.
Pi 4 is mature, widely supported, and great for most projects. Pi 5 offers higher performance and PCIe/NVMe via FFC—choose it for heavier desktops and faster storage.
Yes. Pi 4 supports USB boot—use a reliable USB-to-SATA/NVMe adapter and a good PSU.
Yes—the 40-pin header keeps the classic Raspberry Pi pinout. Confirm power/cooling needs for demanding HATs.
Yes—fast shipping anywhere in the Philippines. Same-day processing on in-stock orders before cutoff.
