Hi my 13 year old I are brand new to arduino (specifically an Intel Galileo board) and bought your RGB Matrix Backpack v1 at the Seattle Makers Fair. We have fallowed the instructions for performing the soldering, but are now stuck due to being SO new. We bought a 10 pin ribbon cable and have plugged it into the backpack and have stripped the wires on the other end. Any help in figuring out which of pins 1-13 to put each wire on the cable into would be very helpful and keep us going on our new technical adventure.

Any help is greatly appreciated.

Digital pins 1-13 on the Galileo do not carry any of the signals you need. You only need four of the ten wires — 5V, ground, SCL, and SDA. The legend on the back of the board shows which is which. Also note that the 10 pin connector is intended to go on the back side of the board, where the legend for it is.

Assuming you have the ribbon cable set up so that the colored stripe is on the same side of the connector as the molded-in arrow, and your connector is on the back side, the stripe is pin 1 and the other pins count from there.

All that said, the four signals that need to be connected connect to the pins with the matching labels on the Galileo. 5V and GND connect to the corresponding pins in the power connector. SDA and SCL connect to the corresponding pins on the same row with digital pins 8-13.

Is that all reasonably clear?
