FAQ
● Can it directly display the battery power? How is it used to display the battery power level?
It is not possible to display directly. The measurement voltage and 7-segment display driver board need to be added.
● Can the wires be extended?
The wires should not be too long, but can be extended to about 1m.
● How many 7-segment LED displays can be connected to the driver board?
Up to 4 LED displays can be connected to the drive board.
● Is the input voltage related to the brightness?
The higher the voltage the greater the brightness, but overvoltage and overcurrent will cause damage to the LED display. Use external current-limiting resistors.
● Can the interface pass through the holes on the end cap?
Bend it slightly to pass through the holes of Ø10.1±0.1.
● Is there an internal driver board?
No. The inside is only 8 direct leads for the LED display, so an external driver board is required.
