With TM1638 Chip, this module gathers more than three common SCM peripheral circuits. The advantage is only three IO ports will be occupied when it drives. SCM doesn't need to work for scanning display and key scanning. It only need to read the relevant register to send display data or test button so it saves MCU resources effectively. Keys are sensitive and display effectively. VCC GND 5V power supply, STB CLK DIO SCM IO port.
