The Geppetto design tool is an in-browser application for designing IoT, edge, and ARM-based server hardware. Its goal is to accelerate the prototyping stage and low-volume production of these products by automating most of the production pipeline. In fact, Gumstix has been designing its own boards in Geppetto for years. Here are a few helpful links.
Geppetto includes in its library of hardware modules several arm-based compute options:
There is a $1999 one-time manufacturing fee and a 15-day delivery target. This means quick turnaround at a low cost.
Here are some Geppetto features:
The best way to get acquainted with these features is to try them out. A good "hello world" would be to use board builder to create a Raspberry Pi CM3 carrier board with a USB port and serial console using the board builder.
In this thread, we will be answering questions, and providing design examples and any kind of Geppetto assistance you may need.
