Module – TM1651 – LED segment displays
Hardware
Let op: Aansturing dmv microcontroller, dit is niet direct een voltmeter om op een batterij aan te sluiten!
Informatie (ENG)
This is battery level display module based on battery style digital tube LED. It contains 10 segments LEDs.
There is driver chip TM1651 onboard, so the control interface is simple, just two signal lines and VCC / GND. It can be used to display the battery power.
Features:
– Compatible with UNO R3
– It is suitable for battery indicators and you can read it in the sun
– Color: Red
– 8 adjustable luminance levels
– Working voltage: 3.3-5.5VDC
– Working current: 20mA(MAX)
– Logic level voltage: 3.3V / 5V
