AJMRTC 2Pcs 0.36 Inch 4-Digit 7-Segment LED Display Module, Red Common Anode Digital Tube with Colon, TM1637 Driver Chip, 2-Wire Serial Control for Arduino, STM32, Raspberry Pi DIY Clock Counter Proje

AJMRTC TM1637 4-digit segment display module adopts 0.36-inch red common anode digital tube with colon point, perfect for making electronic clocks and numerical readout units. Integrated TM1637 drive chip handles scan and refresh internally, so you only need two control wires instead of driving every segment separately, greatly simplifying your programming work. It supports 8 grades of brightness adjustment to adapt dark rooms and bright workbenches. The module works stably with Arduino, ESP32, STM32, Raspberry Pi and other mainstream microcontrollers. You can display time, counting values, temperature, voltage and other real-time data. Four M2 mounting holes are reserved on PCB for fixed installation inside enclosures and DIY instruments. This listing contains two modules, convenient for dual data display or spare use. Please note this is common anode type; confirm your code library matches common anode definition before powering on.
