€3.50
Tax included

DS1302 Real Time Clock Module with CR1220 backup battery (non-rechargeable, >10 years data retention). 3.3V/5V operating voltage, compatible with Arduino and microcontrollers.

Quantity

The DS1302 Real-Time Clock (RTC) module features a CR1220 backup battery to maintain time and date during power outages. This 8-pin SMD chip operates with a 32.768 kHz crystal and provides a theoretical data retention period of over 10 years.

Compatible with both 3.3 V and 5 V supply voltages, this module is suitable for Arduino microcontrollers and other platforms. Communication uses three pins: CLK (clock), DAT (data), and RST (reset).
