Receiver heat mainly by the receiver chip type and number of internal decisions. Promise for wireless presenter products, there are three types of receiver: a receiver or a general call pure receiver. Integrated Micro SD card receiver. U disk integrated receiver. Ordinary USB receiver is a little heat, touch, when only warm feeling. Micro SD card reader integrated receiver, a USB HUB within multi-chip, a card reader control chip, divergent big receiver than normal. TheGreen laser pointerwith remote control is of the high quality. U disk integrated heat sink maximum. And compared with ordinary receivers, integrated receiver U disk more than once within a three-chip: USB HUB chip, USB host chip and Flash chip. These three chips larger than the heat, add up to three relatively hot chips. U disk read and write frequently in time, this phenomenon is more obvious, its maximum internal temperature can reach 60 degrees. But it is still within the scope of the design does not affect the use of the product. Promise for the integration of wireless presenter products are the industry's mainstream chip brand in the heat control is a leader. If you can read U disk, USB controller chips may be a problem or Flash chips. In this case, as long as the USB HUB chip is working properly, the receiver is normally used. green laser pointeris a new type of patented electronic product. U disk with the receiver is equivalent to a U-disk storage, its use and the same general U disk. Promise as a wireless presenter products in the factory have been virus checked, not with the virus. If in the course of infection, virus can be just, will not affect the function of the product page. Micro SD (Secure Digital) card, also known as TF (TransFlash) card for small portable memory cards, commonly used in mobile phones, digital cameras and other products. Receiver Integrated Micro SD card reader, is that users can put the Micro SD card into the card slot of the receiver, as a U disk to use. Micro SD card on the phone can be used directly. green laser pointeris especially designed for the computer. As the SD (Secure Digital) memory card with short, light and portable, features a large storage space, plus a large number of electronic products use this specification, the so-called SD / SDHC (Secure Digital High Capacity) memory card is now available called is the mainstream of data storage market. But also because more and more new products more advanced options to the SD card as storage interface, coupled with consumers increasing demands for storage space, SD Association (SD Association, SDA) with the tide in the spring of 2009 the U.S. CES Consumer Electronics Show announced the new SDXC (Secure Digital Extended Capacity) standard.green laser pointeris specifically designed for the multimedia projector. SDXC storage limit to 2TB (2048GB), interface to read and write speeds of up to 104MB / s (and future development to 300MB / s), can provide more high-speed transmission needs, while using the latest exFAT file format, to improve the memory card itself and the interaction between related applications compatibility. In addition, the new SDXC specification, but also the addition of the new design structure UHS, UHS-1 represents the Ultra-High Speed Bus 1, allows transmission speeds of up to 104MB / s, and raised to the future development of 300MB / s. green laser pointerhas gained the increasing popularity in American countries.
