Interface DS3231 Precision RTC Module with Arduino

DS3231 Vs DS1307

The main difference between the DS3231 and DS1370 is the accuracy of time-keeping.

DS1307 comes with an external 32kHz crystal for time-keeping whose oscillation frequency is easily affected by external temperature. This usually results with the clock being off by around five or so minutes per month.

However, the DS3231 is much more accurate, as it comes with an internal Temperature Compensated Crystal Oscillator(TCXO) which isn’t affected by temperature, making it accurate down to a few minutes per year at the most.

DS1307 is still a great value RTC and serves you well, but for projects that require more accurate time-keeping, DS3231 is recommended.

obb files to SD card

If you want to store obb files to external storage, there’s only one viable option that I found.

It’s fbind magisk module originally created by @VR25 and updated by @Hooin Kyoma. Here’s link to updated fbind module.

To use this, install termux terminal app. Type “su”. Approve root access. Type “fbind”. Type “3”.
Type “1” to move everything from Android/obb to external
Type “2” to move specific folder and then type the name of the folder you want to move.

It’s also advisable to have SD card that has “A1” or “A2” app class for better IO performance.
