Serial Driver For Large Seven Segment LED Displays (PCB Only)

Description:

Seven segment LED displays are visually very charming and are readable from a far viewing distance and wider view angle compared to other types of electronic displays. Small size seven segment LED display modules usually require a forward driving voltage less than +5V and as such they can be driven directly through a microcontroller's I/O pins. However, in order to interface bigger size seven segment modules, which require more current and a higher forward voltage, an additional voltage translation circuit is required to enhance the microcontroller outputs. This display driver allows you to interface 8 large seven segment LED display modules (common-cathode type) to a +5V microcontroller through an SPI interface. It can drive LED segments with forward voltage up to 24V.
