Although I don't have all the components yet, I was curious to test the fit of the ones that have already arrived. I was especially interested in the fit of the debug connector, as it is the first time I am using a connector in this configuration (i.e. in plane with the board and with contacts on both sides of the board). Turns out the connector fits perfectly. If anything the fit is a bit tighter then I thought it would be.

While I was at it, I also dropped on the battery holder. As of now, I did not solder anything. I want to start populating the board with the ICs, as I would think that they are the trickiest parts.
