2-7pack Battery Power LED Bar Display Module Kits 10 Segments DIY LM3914 Kits

Description: This is a DIY kits,need buyer to assemble it. 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, 10 LED display, either Multi-light bar display or a single light dot display.10 LED Displays the battery voltage,bar display full brightness 42mA, single light shows 4mA.Support: single lithium 1S (4.2V) ~ 4S (16.8V), lead acid 6V ~ 12V, NiMH 3.6V ~ 18V, nickel-cadmium batteries 3.6V ~ 18V. Specification: Power: bar display full brightness 42mA, single light shows 4mAMeasuring range: the battery inside the common 2.4-20vDisplay: Multi-light bar display or a single light dot displaySize：45x14 mm / 1.77x0.55 inch Package Includes: 1 Piece modules6 Pieces accessories(Assorted Quatity for You Choose) Note: To adjust their voltage, according to the method of adjusting the order, to emphasize high-end, then adjust the low then positive, then negative black, must not be reversed, this module is the maximum limit voltage DC 20V, please use anti-static welding or soldering station pull electric heat welding.Please allow slightly difference due to manual measurement.
