EChucK Standards Subject description: So everything works together... |

I copied and pasted the following text from the EChucK web site, it is the beginnings of a standard for EChucK. Please feel free to post with critiques and changes, suggestions, or comments. Here is the text:

The EChucK standards comittee which consitsts of, um... just me, has suggested the following standards for EChucK development. If you wish to contribute to the growing collection of EChucK hardware and software, please stick to these standards or else all heck will break loose and nobody's modules will work with anybody else's modules. 'Nuff said.

Use Eagle PCB CAD to capture your schematic(s), lay out the board(s), and generate the Gerber files. If you have another PCB CAD program that you prefer to use, you are welcome to do so, but you would be labelling yourself as a trouble-making renegade because most other users will not be able to read and edit your files. Please consider being a nice law-abiding citizen and using Eagle, it will make things better for everyone.
Input power is from a single 9V battery or 9V wall-wart. If your chosen power module has a wider range of input voltage capability, then you may use a wall-wort that is within that range. In the future, other battery types and solar cells may be used for input power.
Output power, which is the power that goes to each module, is +3.3V.
Power is distributed from a central power module. Each module that requires power has two power connectors, on on the lower left and one on the lower right. The left one is intended for receiving power and the right one is intended for delivering power. When hooking up a circuit, it is important to prevent power and ground loops by arranging them in a tree structure.
Artificial ground, if required by a particular module, is generated by a voltage divider module.
Connections between modules are done with miniature screw terminals for quick, reliable, multi-conductor connections. The cost of these modules is approximately 0.40 to 0.50 dollars US per node, so they become the major cost contributor of the system. This is still a good price as there seems to be no viable alternative. However if you are making a permanent circuit, you may wish to leave the connectors off and just solder wires in place.
