RTC Module

RTC DS3231M Module - I2C

With this RTC (Real Time Clock), the BEEP base can keep track of time. Additionally, this module includes a battery holder for a CR-1220 battery. When the main power supply of the BEEP base fails or the BEEP base is turned off, the battery will temporarily take over to keep the RTC running.

Specifications:

• Supply Voltage: 2.3-5.5V DC
• Signal Voltage: 2.3-5.5V
• Communication Protocol: I2C
• RTC Chip: DS3231M
• Clock Accuracy: ~5ppm (~0.432 seconds/day)
• Battery*: CR1220

*The module also works without a battery; it is only needed if the RTC needs to continue working when the power supply fails.

Package Contents:

• 1x RTC DS3231M Module (with battery)
• 1x Male header set, soldered
