Normally this would not be a problem but we are finding these things out after the fact ~~and need to~~ scramble to try and get it all to work properly~~. These are only guidelines and should not be treated as gospel~~. We ask you to adhere to these guidelines when designing new PCB's if you can. If you need to deviate from these guidelines we ask that you specify the deviation in the assembly notes and list that when releasing your design. This way others will know if there are any compatibility issues. If you are populating a circuit board please double check to make sure these guidelines were followed before you start populating your board based on what you read on this page. <br>		This is the area we, the DIY community, will list some general Hardware Design Guidelines for circuit boards and electronic devices.
