While creating the board layout, I realized (too late!) that the package I choose for the MSP430 was not available. I selected the MSP430FR5947 MSU because it has the same features of the MSP4305969 mounted on the LaunchPad but in a more handy TSSOP38 package. However this part is hard to find so I have to give up.
On the other hand, the MSP4305969 has a 48RGZ package, which determines a significant rise in costs because I for sure will never be able to place and solder such a small chip without making short-circuits. So I will have to ask some company specialized in surface mounting technique to solder the MSP43 and this definitely will make the budget I planned for this challenge to be over...
So I switched to the Boosterpack approach: I redesigned the board to plugin into the Launchpad. This is the result
I created the Gerber files and sent it to Wurth Elektronik PCB service. Now I'm waiting for the PCB. In the meantime, let's get the components and write down some software...
