Prototyping board thoughts

[darconeous]

I had a look at your TRÅDRI dev board, and I had a few comments and suggestions that I think would allow the board to be more versatile and more generally useful:

• Redesign the board in such a way that allows it to be plugged into a breadboard if the headers are soldered facing down instead of facing upward.
• Remove the reset button. If you need a reset button for a project, it is easy to add on a breadboard. Removing the button should allow you to shrink the size of the board considerably, allowing it to more easily fit on a breadboard.
• Remove the power LED. It is easy to add a power LED on a breadboard, and having a LED on this board will throw off power measurements.
• Remove the bypass caps. All of the capacitors that are required by the EFR32 datasheet are already integrated into the module.
• In order to be as conservative as possible, remove all of the copper fill directly under the module. Copper fill on the other side of the PCB might be fine as long as it is kept far away from the antenna, but many modules like this explicitly forbid copper fill anywhere under them.
• Leave the antenna hanging off the end of the board, as seen here
• Keep the debug headers. Those are often useful, and having to always hook them up manually on a breadboard would be a pain.
• Shrink the board to be as small as possible, to help make usage with a breadboard more easy.

Hi @darconeous, feel free to design one and contribute one. I can agree with most of your comments and suggestions, but I never designed this one for breadboards :-)
