Quick Answer: The LabEquip Real-Time Clock (RTC) Module keeps accurate time and calendar data for microcontroller projects, using an I2C interface so an Arduino-style board can read seconds, minutes, hours, day, date, month and year even after it is powered off.
Description
The LabEquip Real-Time Clock Module is a small RTC timekeeping board built around an RTC integrated circuit (such as a DS1307/DS3231-class chip, depending on the specific model supplied) that communicates with a host microcontroller over the I2C interface. It supplies accurate time and calendar data — seconds, minutes, hours, day, date, month and year — independently of the main program, which is essential for projects like data loggers, digital clocks, timers and automation systems.
Many RTC modules include support for a small backup battery so the module can keep track of time even when the main board is powered down, though whether a backup battery is fitted/included can vary by model configuration. This makes the module a common choice in embedded systems, IoT and automation coursework where students need to timestamp events or trigger actions on a schedule.

Compatibility & Safety Note
- Communicates over I2C (SDA/SCL), which is supported by most Arduino-style and similar microcontroller boards.
- Connect VCC/GND correctly before powering on; reversed connections can damage the RTC IC.
- If your module carries a backup coin-cell battery, replace it with the same battery type and observe correct polarity.
- Avoid exposing the board to moisture or static discharge during handling.
