Description

7 Segment Display - Red 15cm (6.5") Large Display Font

This display really is 15cm (6.5") tall! This very large 7-segment display can be seen from a hundred feet away and can easily be driven from an Arduino, Pi or similar.
Each segment must be limited to 20mA. To use this display you will need a 12V supply and current limiting resistors on each segment. Your power supply should be rated for a minimum of 160mA for each digit in your overall display. For example, a 4 digit display will work nicely with a 12V/1A supply.
Or if you want an easy way to drive this display(s) using a minimum amount of data lines, you can use our high-power Shifter Board using only 3 i/o pins

    Hi, here is a project I am working on, I am driving the display directly with TPIC6B595 high-powered shift registers and 47ohm series resistors from a 13.8V supply. Average current drawn by the whole display is just over 0.5A. The brightness of the displa

    Ah, now i understand you. These are pull up resistors, so that the cathodes are pulled up to 12V to switch off, then driven low by the shift resistor.If you need constant brightness across each segment you could be individual limiting resistors in betwee

    The current limiting resistor is there to protect the LED segment from blowing.Without the Resistor the LED is free to take any current the supply can give it, the resistor is there to stop this from happening.You need 20mA for a nice brightness.We use

    The voltage drop across each LED segment is just under 12V
