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 4mA - Measuring range: the battery inside the common 2.4-20v - Display: Multi-light bar display or a single light dot display - Size?45x14 mm / 1.77x0.55 inch
Package Includes:
1 Piece modules 6 Pieces accessories
Note:
To adjust their voltage, according to the method of adjusting the order, to emphasize high-end, then adjust the low end.Red 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.
