Motorola has launched a series of advertisements, ridiculing the Apple iPad is a large mobile phone, and this price also shows that Xoom has full confidence to challenge the iPad. Not to mention recent rumors that the iPad 2 to be released in April will significantly reduce the price.
Xoom's price is also much higher than the current best-selling Android tablet Galaxy Tab, which was sold at a bare metal price of 600 US dollars, but Verizon lowered its price to 500 US dollars earlier this month. The industry believes that the Galaxy Tab is the real large-size mobile phone. Apart from the 7-inch screen, the product also uses the Android 2.3 system designed for mobile phones, but not with the Android 3.0 (Honeycomb) system. The latter is Google's first system for tablets.
In the process of confrontation with the iPhone, Android phones mainly compete with price advantage. The above prices show that Motorola is not prepared to adopt the same strategy.
Dual Color Controller are generally designed voltage 12V-36V, the number of each circuit LED 3-6 in series, current limiting resistor buck, each loop current of 20mA or less. A product of a plurality of LED circuit LED, the advantage of low pressure, simple structure, easy to design;
Dual Color Controller Drawback is: when the current large scale product, you need to configure the low-voltage switching power supply. Due to the limited shortcomings of products, low-voltage long-distance transmission is not possible, all led light bar controller [1] is limited to the small size of the product, such as text signs, small patterns and so on. According to this feature.
The controller design specifications of Dual Color Controller : 12V selection of 75A / 30V MOS power of control, the output current 8A / Road; 24-36V selection 60A / 50V MOS power of control, the output current of 5A / road. Users can control large ones selected according to the above specifications of Dual Color Controller, the transitions can choose to buy NE10 NE20 series of low pressure to low pressure controller series, the gradient. Note that LED must be common anode (+) pole connection method, controller Yin (-) pole, the controller does not include low voltage power supply.
Features Dual Color Controller to control more than large ones, to control the use of the serial signal transmission purposes, the general control unit 512 need only four control connection, serial LED controller LED light sources require board register with the controller can choose models NE040S controller, the controller has reached maximum capacity 4096KBit, if the load 512 LED unit 8192 can achieve maximum picture frame.
Mingxue Optoelectronics Co.,Ltd. has apply the I S O 9 0 0 1: 2 0 0 8 international quality management system certificate, for Dual Color Controller we apply the CE, RoHS and SAA certificate for our led lighting product.
