Single-core tinned copper wire is used, which is easy to weld and anti-oxidation, and is not easy to break. The copper wire can withstand a high temperature of 80°C, making it suitable for a variety of thermal overload applications. The single-strand copper core has strong resistance to tension and surge current, which is convenient for shaping. Packaged by reel, the copper core has a moderate diameter and clear lines, making it easy to use and store. Copper wire is suitable for welding notebooks, motherboards, LCD screens, displays and other circuit boards.

OV7670 image sensor, small size, low operating voltage, and provides all the features of the single-chip VGA camera and image processor. Through the SCCB bus control, you can output the entire frame, sub-sampled, take the window way affect the data resolution of 8 bits. VGA image of the product is up to 30 frames / sec. Users can fully control the image quality, data format and transmission mode. The process of image processing functions including gamma curves, white balance, saturation, chroma, and so can be programmed through the SCCB interface. OmmiVision image sensor applications unique sensor technology to improve image quality by reducing or eliminating the optical or electronic defect, such as fixed pattern noise, tail-blooming, clear and stable color image.
