J15 – Shield A4 connection. Connect pins 1-2 to have an I2C connection to SDA on the programming header. Connect 2-3 to connect A4 to I/O Pin 12.

J14 – Shield A5 connection. Connect pins 1-2 to have an I2C connection to SCL on the programming header. Connect 2-3 to connect A5 to I/O Pin 13.

A4/A5 on the Shield connection lead to J15/J14 respectively. A4/A5 can be analog inputs or I2C connections depending on how you may want to use them for the shields that you choose. They are not connected to anything to begin with on the CGCOLORMAX2.

If you wish to use A4/A5 for the I2C interface that MMBasic supports, you will want to connect A4 to I/O Pin 12 (J15 pins 2-3) and connect A5 to I/O Pin 13 (J14 pins 2-3).

If you wish to use A4/A5 for the analog interface that MMBasic supports, you will want to connect J15 pins 1-2 and connect J14 pins 1-2.
