After joining this forum over 3 years ago I thought it overdue that I say hello and contribute something that I hope you will find useful.
Attached is a picture of simple booster packs that I make. But are they really a "booster pack"? Hmmm. Debatable!
They are cheap and easy to make and I have made 5 of them. I use them all the time because the whole of each project, including the MSP430, is attached to the booster pack. This means I can switch between projects without re-wiring, I can change the model of MSP430 in seconds and I only need one Launchpad.
