Server Hardware for openplotter?
I do not know your pcb board. You have to look in the datasheet.
Something like this is 5V compatible: (see voltage supply 2,3-5,5V)

Further I do not know the used adressed from the moitessier board. Take a look in the Manual. Normaly there are the i2c adresses described.
If 0x68 is also not used there, you can mount the ds3231.
in etc/modules some of the entrys already exists. Do not paste them again.
After hardware wiring, you can check the availibility with "sudo nano i2cdetect -y 1")

If there is an address conflict, you could perhaps use a I2C multiplexer TCA9548A (https://www.adafruit.com/product/2717 or https://www.aliexpress.com/item/32647486...4c4d0TSkFn).

Thus, the DS3231 conflicts with the Moitessier HAT's MPU9250. Both use the i2c x68 address. If it is not possible to change the address to either the DS3231 or the MPU9250, I think the TCA9548A multiplexer should be used. But now, if I use the multiplexer, the problem of programming arises as I am not capable of it. Can you help me ? I figured out how to physically connect everything, but I don't know how to communicate with Raspberry, MCS, etc. I ask you for help, also because if I succeed, it could be replicated by our fellow sailors. Thanks for the fantastic job you are doing.

Hi, i think you can get overlay problems with a multiplexer...
But have not prove it.
Else you can use a "adress translater" for the clock. Something like this:

This also seems better to me.  But I did research to buy it and found nothing.  Where can I buy it ?

Thats the first i have found as breakout... :

You can direct wire it to the i2c connector on the MCS board...
