6 reviews

FEATURES:


Power display is to take some voltage, perform simulations show the percentage of segments, such as 3.7V lithium battery, take the lower voltage 3V, the upper limit of 4.2V, 4.2-3 = 1.2V, the voltage difference between the lower limit of 1.2V, is the battery Analog power up
LM3914 can accurately detect an analog voltage, and 10 LED display, display dot mode LED is lit 10 one, or in a stripe pattern individually lit LED
Display Description: Displays the battery voltage between the lower limit of 10 files showed that representatives of each of the lights 10% charge displays, on behalf of 10 lights display charge 0% -100% range; you can also change the single light display, is displayed only a light, more power, single-light power 4mA, all bright 42mA.
