Server Hardware for openplotter?

Yes, you can add the DS3231 to the MCS... Connect it to I2C. A guide you can find here. (I have not aprove the install)

Other boards you must proove if the I2C adresses overlabs with the board

I have a RTC PCB with DS3231, it is powered at 3.3v. Can I connect it to the I2C of the MCS since it has 5v output? Then I also mount the Moitessier HAT .... can there be conflicts? If so, how to solve them?
For the configuration side I will have to do this:
Edit the module file
sudo nano / etc / modules
Add the following to the to the end of this file
i2c-bcm2708
i2c-dev
rtc-ds1307
Test the bus
Check your I2C bus with, sudo i2cdetect -y 1. The output should be similar to

i2cdetect output
i2cdetect output
Load the clock at boot
sudo nano /etc/rc.local
Add the following lines before exit 0
echo ds1307 0x68> / sys / class / i2c-adapter / i2c-1 / new_device
hwclock -s
Reboot
Set date and time
When connected to the Internet, the pi automatically gets the date and time from time servers. These are quite accurate. With the command hwclock -s in rc.local, we have set the pi to override this time to match the RTC. This is fine once we have the correct time on the RTC. So let's set it to the correct time.

sudo nptd -g -q - set the pi's system time to Internet time
date - check the system time
sudo hwclock -r - check the date and time of the RTC
sudo hwclock -w - write the system time to the RTC
sudo hwclock -s - set the system time from the RTC
