It is one of the easiest ways to start a design in Geppetto. You just choose and select from a list of functionalities, click a button and the modules will be on your board.
The Geppetto Board Builder is one of the ways to start a Geppetto design.
How to use the Board Builder?
1. Choose functionalities or modules
Select the group you want on the board (e.g. COM or Processor). Board Builder will suggest a list of COM or Processor you can choose from on the left box. If you don't find what you need, use the Search functionality.
2. Click the [Start Build] button.
Board Builder will add and position your modules on the board.
3. Add Power
Board Builder also includes a power suggestion phase. You will enable this feature by following the on-screen prompt after the modules has been added.
4. Review and Finalize
Once you're finished with steps 1-3, you will have a board that's ready for your review and finalization.
The Geppetto workspace contains all the tools to create a board
Drag and Drop
Find modules from the righthand library. Modules are functional blocks that offer a specific feature, such as power, sensors, connectors, and more. To add a module, simply drag and drop its graphic onto your board.
Drag modules with your mouse to position as desired. For more precise placement, you can nudge the module with your keyboard's arrow keys. You should keep modules within the board boundary, and in their own space (ie. not overlapping with another module).
To connect a module, hover over it and and click the requirement flags that appear. Flags allow you to establish dependencies, including power requirements, between specific modules.
Steps to Connect Modules
Color-coded requirement flags will display when you hover over a module. The flag color will indicate what needs to be done.
Connect a red requirement flag
A red flag means that its dependency needs to be fulfilled by a new module from the library. Clicking this flag will make the module library automatically display matching options. Any of these options will fulfill the requirement.
When you add a valid module to your board, the red flag should detect it and turn yellow. You can now connect those two modules via their flags.
Connect a yellow requirement flag
A yellow flag means that another module on your board can fulfill its requirement.
A connection is complete when the flag turns green. You can check where the module is connected by clicking this flag.
Disconnecting a module
The requirement flag should now become yellow, meaning it has disconnected.
- Right click on the module and select “ROTATE”
- Or double click on the module
- Or click on the module and press R on your keyboard.
The module will then rotate 90 degrees counter clockwise. Repeat until you achieve the desired rotation.
- Right click on the module and select “DELETE”
- Or click on the module and press Delete on your keyboard.
Colors indicate the status of your board and modules. Find explanations of each status below.
A dependency or requirement is missing from the board.
Some connections have not been met, but can be satisfied by an existing module on the board.
All dependencies have been met.
The module cannot be placed here. Placement can be invalid if it is off the board, or overlapping with another module.
Black / Gray
The module can be physically placed here.
The board is incomplete. Either the module is not properly placed within the board, a dependency is missing from the board, or both.
There are unresolved connections between the modules on the board.
All connections and dependencies have been met. The board is ready to be submitted for verification.

Allows the requirement flags to appear, which represent the connections that are necessary for a module on the board. You can only connect modules while this mode is toggled on.
Please note that Connections mode disables Dimensions mode, and vice versa.
Allows you to control your board size, set the distance between the edge of the board and a module, or the distance between two modules.
Steps to set dimensions
First ensure that Dimensions mode is on. Then, hover over the edge of the area to be measured until you see a dashed line.
Your dimension should now appear. Geppetto recognizes measurements in increments of 0.5mm. You can input a value to adjust the distance, and right-click to lock the dimension. Lastly, you can also use this mode to view the static size of any module.
Module Info mode
Allows you to see module information and access the data sheets for components associated with the module. To view the information, click a module while this mode is toggled on.
Tabs: My Account, Designed in Gumstix, Community, and Shared with Me
Besides the workspace, other tabs in the top bar offer extra functionalities:
You can sign in via your Google or Yahoo account, or use your e-mail address to create a Geppetto account. Once logged in, your saved designs will display here.
