Gallop43 Expansion Board
LCD Side of Board
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. Screws and nuts of this size tend to loosen easily without locking washers.

- The topmost connector, positioned above the Reset button, is the USB OTG connector.
- Directly under the Reset button is the audio connector.
- Directly under GPIO21 and (D2) is the USB Console connector.
- Directly under D9, D10, and D8 is the external battery connector.
- Just under the "Power On" button is the external power (wall wart) connector.
