About this product
A real-time clock module built around the DS1302 chip, which tracks seconds, minutes, hours, day, date, month and year. It can run from a backup battery when main power is off, and communicates over a three-wire serial interface. It is common in Arduino and ESP projects for timekeeping and data logging.

Frequently asked questions
What is the price of DS1302 Trickle-Charge Real-Time Clock (RTC) Module in Egypt?
DS1302 Trickle-Charge Real-Time Clock (RTC) Module currently costs 85.5 EGP in Egypt.
Where can I buy DS1302 Trickle-Charge Real-Time Clock (RTC) Module in Egypt?
DS1302 Trickle-Charge Real-Time Clock (RTC) Module is available from UGE. Compare the offers above to find the best price.
How do I wire the DS1302 to an Arduino or ESP32?
Connect VCC and GND, then CLK, DAT and RST (also called CE) to any digital pins. It is not an I2C device, so SDA and SCL are not used. A DS1302 library handles the three-wire protocol.
Does the clock keep time when the main power is off?
Yes, if a coin cell is installed in the holder. Keep the backup battery in place to preserve time and date during power loss, and replace it when the time starts resetting after power-off.
