The Gallop43 expansion board offers numerous features to help you make the most of your Overo COM. This discussion will begin with closeup photos of various parts of the Gallop43. Because many users buy an LCD to go with their Gallop43, we will begin with a tour of the buttons found on the right side of the LCD surface of the board, which is the surface you will normally see if you use the LCD a lot. Also shown in this photo are the connectors populating the right edge of Overo COM side of the board -- that is, what connectors are on the other side of those user buttons.

Corner Holes

The holes on each corner of the Gallop43 appear to be sized for 2-56 screws.

The buttons are marked, from top to bottom:

LEDs

LED's are marked, from top to bottom:

GPIO21 (D2)

D9

D10

The purpose and colors of some of these LEDs are unknown. D10 possibly turns on, glowing red, to indicate the external battery is charging.
