I am designing my own daughter board that must work in conjunction with the X728 DC UPS. I need to use several GPIO pins, but want to make sure I don't cause a conflict between my the board I am designing and the X728 DC UPS. I know that you use I2C on pins 3 and 5, and I believe you also use GPIO5 and GPIO12. You use Pins 2,4 for power too. Are there any other GPIO pins used by the X728 DC UPS, or am I free to use all the rest of the GPIO port?
