Bare-Metal Micro

Now that I know the flash memory chip will work with the Game Boy, I have started designing a PCB in KiCad that will contain a surface mount version of the flash chip and headers to break-out the the cartridge connector pins, as well as, the pins on the flash memory that are not connected to the Game Boy.

I have learned a few things from the first break-out board I designed a couple years ago:

1. The cartridge must lie flat inside the cartrige housing. Therefore, I must use surface mount headers instead of throughhole ones.
2. The outline of the board was slightly off, causing the small hole to be misaligned with the cartrige housing.
3. The board thickness needs to be smaller. I used 1.0mm before and that is just a tad too much. This time I am going down to 0.8mm.

I am mostly done with the new design. I want to double check all the mearsurements and make sure that I can source the right headers before I send it off to be made.
