4 Bits Digital Tube Led Display Module With Clock

2Pcs 4 Bits Digital Tube LED Display Module Board With Clock For Features: The module is a 10 foot with a clock point, with four common anode tube (0.36 inch) display module for driver IC 595, only two signal lines can make the MCU control 4 digit 7 segment digital tube. It has 24 hour timing error correction settings, can set every 24 hours error correction, setting range is -9 to 9 seconds. (Note: To make this effective, it must be 24 hours of continuous power) 4 display modes: A. display time; B. display data; C. display temperature; D. alternate display time, data and temperature. Specification: Size: 42 x 24 x 12 mm Temperature display range: -9 to 60C Temperature error correction setting feature, set the range: -5 to 5C Working voltage: 3.3V~5V. (Note: the lower the voltage, the lower the luminance, the lower the power consumption) Package included: 2 x LED display module board

Introduction: The module is a 12-pin display module with a 4-point common digital tube (0.36 inch) with a clock point. The driver chip is TM1637. It only needs 2 signal lines to enable the MCU to control the 4-bit 8- Segment digital tube. Features: Digital Tube: 4-digit common anode with a 0.36-inch digital tube with a score point, highlighted in red Positioning hole: 4 M2 screw positioning holes, the hole diameter is 2.2mm, which makes the module easy to install and position, and realize the module combination Digital tube 8-level grayscale adjustable Control interface level can be 5V or 3.3V Size: 42 x 24 x 12 mm Weight: 8g Project Minimum value Typical value Maximum Unit Voltage 3.3 5 5.5 VDC Current (@5V) - 30 80 mA Pin Description: GND - ground VCC - the power supply DIO - the data input and output pin CLK - the clock signal pin Overview of the library routines: 1. Clock Display: Use the timer 1 of the MCU on the motherboard to time and let the 4-digit display. 2. Number Flow: 0~9, A, b, C, d, E, F, and other 16 characters flow from right to left. 3. StopWatch: Use the timer 1 of the MCU on the motherboard to time, and use the button to realize the stopwatch function. Experiment equipment: An compatible motherboard Catduino (not familiar with open source hardware can be understood as the Atmega328P microcontroller development board) and a mini USB cable; 1 4-digit digital tube display module; 4 male to female DuPont lines for connecting the control interface of the modu
