SPI7SEGDISP4.40-1R is a serial 4-digit seven segment LED display based on MAXIM’s MAX7219 device. This display module can be interfaced with any microcontroller that has 3 I/O pins available. If the microcontroller features a built-in hardware SPI, then the display module can be interfaced as a SPI slave device. In that case the SPI signal lines SDO (serial data out), SCLK (serial clock), and SS (slave select) from the microcontroller can be directly connected to the DIN, CLK, and LOAD pins labeled on the display module. CS is active low signal.
