Description

Universal PCB for creating clocks and thermometers

Based on this printed circuit board, you can make almost any clock on a 7 segment LED display with a common cathode or with a common anode.

The device uses an 8-bit STM8S103F3P6 microcontroller, a DS3231 real-time clock, a TM1623 display control driver, and a DS18B20 temperature sensor.

The VD1 diode is protected against reverse polarity of the power supply. Also, this project can be used with a display from a DVD player.
