RTC installation instruction for MS3.

[Rotxam]

Hello,
I want to install one real clock module on my MS3 card , I do not find the documentation to perform the work. I only find for the MS3X expansion board.

Can you help me?

The RTC module is designed to be installed on the MS3X card.

Hello.

But, i read this note in diyautotune web site:

This module is intended exclusively for the MS3 and is considerably easier to install if used with an MS3X expansion board.

Note: If you are ordering the real time clock module with an assembled MS3, we can install it in the MS3 for an extra $15 charge.

If i understand, the module can be installed on a MS3 without expansion board?

Thanks

Installing it without the MS3X will require matching up the holes that the RTCC would mount in to wires connected to the 34 pin header on the MS3 daughter board. This chart shows which RTCC mounting hole goes to which pin on the 34 pin header.

H1 - 29
H2 - 27
H3 - 22
H4 - 20
H5 - 31
H6 - 30

See this image for reference for where the holes go:

Thank you for your reply Mr. Cramer.

So, if I understand, this 4 holes , GND, 5V, SDA and SCL, connect to the pin 30, 31, 20 and 22.

This is OK?

Thanks

Yes.
