In engineering circles, this circuit is better known as a 7447 BCD to seven-segment decoder/driver, but just using a single chip has little pedagogical value.
With chips in hand, [limpfish] designed a small breakout board for the MAX7219 and two common anode 4×7 segment displays. These displays can be daisy chained, and connecting them all together ...
The figure shows the circuitry for a two-digit, common-anode display (MAN6710) that can be expanded to any number of digits. Series resistors and the type of latch used limit the segment current.
