Accidentally ordered unthreaded spacers instead of threaded standoffs to mount the board(s).

Upon having 3 boards fabricated by OSH Park, the resonator is seen to not be connected to the ground plane. Running the ratsnest again on the Eagle board file shows that the resonator is via-ed to a plane, but this plane is not connected anywhere.

After having 3 boards fabricated by OSH Park, I plugged in the 3.3V FTDI Basic breakout to load a sketch. Both the RX and TX lights went solid (and brighter than normal), and the FTDI chip itself began getting very hot.

The COM port that is created by the FTDI interface is also dropped immediately as the interface is plugged into the board.

Thought I'd be smart and use polarized headers with matching housings, but upon assembling one board with them I find they are just not necessary. Some headers have tabs on top, others on bottom, and some headers need to be flipped to the underside of the board just to get the connector in the right orientation.

Find better, non-polarized housings and revert to bare right-angle male headers.

If a user wants to connect the Lumiboard to an I2C device, such as a compass, GPS or I2C-safe level shifter, they need access to the board's 3.3V and GND lines, as well as the SDA and SCL lines. Currently, only the SDA and SCL lines are broken out, so add a 2-pin male header that can be used for this purpose.

Currently, the 32-TFQN ATMEGA328P chips must have the Arduino bootloader burned onto them externally using a breakout board. This will increase build time and complexity, and is also a pain in the ass. A 6-pin ICSP header should be added so the bootloader can be flashed after the ATMEGA is soldered to the board.
