Frequently Asked Questions
Does this module include the backup battery?
No. You must provide a CR1220 button cell battery separately to enable the 5+ year backup function.
Can I use this RTC with Raspberry Pi Zero?
Yes. The DS3231 board is compatible with any Raspberry Pi model (Zero, A+, B+, Pi 1, Pi 2, Pi 3, etc.) using the I2C pins.
How do I synchronize the system clock to the DS3231 after reboot?
After enabling the RTC overlay and rebooting, run “sudo hwclock -r” to read the RTC time and “sudo hwclock -s” to set the Pi’s system clock from the DS3231.
