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 RF4 RF-C39 4K Dual-Spectral Thermal Camera is a professional diagnostic tool designed for electronics repair technicians, microsoldering specialists, and PCB troubleshooting applications. Combining a high-resolution 4K visible-light camera with infrared thermal imaging, it helps users identify overheating components, locate potential short circuits, and diagnose faults on printed circuit boards (PCBs) and electronic device motherboards.
Ideal for smartphone, tablet, laptop, and other electronic circuit board repairs, the RF-C39 supports microscope integration and HDMI display output for detailed inspection. Its dual-spectral imaging capability allows technicians to compare visible images with thermal views, making it easier to pinpoint heat-related faults during troubleshooting.
Dual-Spectral Imaging: Combines visible-light imaging and infrared thermal imaging for improved circuit board diagnostics.
4K Ultra-HD Camera: Features an 8.29-megapixel Sony CMOS sensor for detailed inspection and documentation.
Short Circuit Detection: Helps identify abnormal heat patterns and potentially faulty electronic components.
High-Resolution Output: Supports HDMI output at 3840 × 2160 at 30 fps and 1920 × 1080 at 60 fps.
Microscope Compatibility: Features a CS lens interface for compatible trinocular stereo microscope setups.
Adjustable Image Settings: Supports manual and automatic exposure, adjustable brightness, and white balance controls.
Customizable Guide Lines: Includes a center crosshair and up to eight adjustable guide lines for precise inspection.
Photo and Video Capture: Supports image and video recording, with USB flash drive storage.
Standalone Operation: Can operate with an HDMI display without requiring a computer or smartphone.
User-Friendly Controls: Supports USB mouse operation and multiple menu languages.
