Serial 7-seg Display Board
IC/Module: MAX7219 LED Display Driver
MAX7219 is a serially interfaced 8-digit LED display driver IC equipped with a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM for storing digits. The external resistor is required to set the segment current for all LEDs. This display driver allows the user to select code-B decoding or no-decode for each digit.
The position setting of SMD jumpers depends on the development system to connect to. By default, the jumpers are set to PIC position. In case, the user wants to use it with AVR/8051 development systems, the user must unsolder them and resolder them in the AVR/8051 position.
