KitsGuru TM1638 Eight 8 - Bit LED Digital Tube Display module 8 Keys Seven Segment Display Lights Electronic Hobby Kit

The module is used in chip TM1638, a collection of these three common MCU peripheral circuit, the biggest feature is just take three microcontroller IO port to drive, do not need to scan display and key scanning microcontroller intervention, only need to read the relevant register send display data or test button, save MCU resources. We usually use an external microcontroller 8 LED, 8 digital tube, 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. Including: 8 buttons, 8 LED, 8 digital tube, common cathode LED digital tube, such as STC microcontroller can be directly connected. Voltage: DC5V. 1. 8 buttons. 2. 8 LED. 3. 8 digital control, common cathode LED digital tube. 4. STC and the like can be directly connected to the microcontroller. 5. Weight:28g. 6. Size:76*50*10mm.
