Featuring eight 7-segment displays, the Serial 7-Seg 8-Digit Board is designed to provide full control of the digit segments including decimal points. The board has a serial
input/output common-cathode display driverMAX7219 that interface microprocessor
to 7-segment numeric LED displays that allow the display of 8 digits, bar-graph displays, or 64 individual LEDs.
The Serial 7-Segment 8-Digit Board uses the industry-standard Serial Peripheral Interface (SPI) for communication with a host microcontroller. The display driver is connected to multiple common-cathodes LED displays.
