We usually use an external microcontroller 8 LED, 8 digital tubes, eight keys which will occupy the number of IO ports, far more than three IO mouth it, but with this module can be achieved. The practical application of key sensitive display good results. Wiring: VCC GND connected to 5V power supply, STB CLK DIO connected microcontroller IO port. The module comes with 8 buttons, 8 LED, 8 digital tube, common cathode LED digital tube, such as STC microcontroller can be directly connected\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003eFeatures: \u003c\/span\u003e\u003c\/h2\u003e\n\u003cstrong\u003eEfficient Drive Chip:\u003c\/strong\u003e Utilizes the TM1638 chip to drive a common cathode LED digital tube effectively.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e3×8 Button Expansion:\u003c\/strong\u003e Capable of extending up to 3×8 buttons for versatile input options.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eIndependent Control:\u003c\/strong\u003e Supports separate control of LED digital tubes and buttons for flexibility in design.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAdjustable Brightness:\u003c\/strong\u003e Offers 8 levels of brightness control for LED digital tubes and LEDs, using a unified brightness setting.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCascading Capability:\u003c\/strong\u003e Allows cascading up to 6 modules of the same type for larger setups.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eEasy Wiring:\u003c\/strong\u003e Includes simple wiring options—VCC and GND for 5V power supply;
