This module is a 12 foot with a clock point, with 4 bits common anode tube (0.36 inch) display module for driver TM1637, only two signal lines can make the MCU control 4 bits 8-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).
