The new board has a CPU with more "legs" that provides extra input/output signals for more advanced projects, but it is said to be compatible with the smaller chip that comes in the older board.
The connection points are soldered into the new board as well, and in the case of the older board they were packaged in the box for the end user to solder in and use if needed. TI makes some plug-in boards that sit on top of these connections and plug in and they decided to mount the pins on the Launchpad because some end users were not good at soldering but wanted to use the add on boards. They made a decision to just solder them on all boards. It doesn't affect the operation but for some applications that don't need the pins on the main board they are a small annoyance. It is easier to solder wires to the board with the holes left open.
We have known for several months that there were new boards released but there's no way to know when placing an order if you will get a new one or old one if a supplier has stock of the old one. Both boards have the same ordering code so you cannot tell which one you are getting.
In the end the new board should work just fine. You may get a warning message when loading the firmware into the chip. If you do get an error let us know and we will try and document a correction. The programming software should ask if you want to program anyway and if you say yes it should work fine.
Thanks for sharing the update. let us know if you have any problems with the new board, so we can get on it right away.
Thanks for replying so quick! I am thinking about getting some plugs for it- on some model planes i have there are connections like those on the side with a plug it goes into. So maybe I can get some of those and use them instead of soldering. That way i could esily replace the board if it breaks.
Also, can i use a 9v battery for some 5v servos? I could use 3 or 4 AAs but I would rather not have the weight.
You really need to look up the servo specification to be sure that it can handle 9 volts. That is probably more voltage than most servos can handle. But it could vary from one model to another.
You could try finding depleted 9V batteries that have 6 volts or so left in them and use those. Go around and replace all the smoke detector batteries in your house and check the voltages. You could find a depleted one, plus you have made a safer home.
