++ for the wiki idea for fully qualified boards, place to put source code, fixes, firmware, schematics what not. Wiki can be alot easier to read through for a beginner than a 15 page forum post

Thanks for all the help Zeke. They turned out beautiful....
 

 

If all else fails, you can always use Elpotronics' FET-Pro430 Lite to make the LaunchPad a standalone programmer.

Just got an answer over at e2e about licensing:

I just got my upgrade email which I use at work.

I stumbled across Autotrax DEX tonight.
 
Since it's priced at $99 I had low expectations but it's better than I expected. Much better.
 
Has anyone else tried it out yet?

I spotted this article on Websockets via HaD today: http://blaisejarrett.com/websockets/
 
Is anyone out there tinkering with Websockets?
 
It's the kind of thing that I think is really cool.

Oh come on! I've been doing that for almost a year now. :roll:
 
Yup. It's time for me to go to bed. :crazy:

I believe cdch10 did post the url in the original post.

He just couldn't linkify it yet.

Hello All,
This is to let you all know that The 43oh Store is now open. There are just three products for now Launchpad, Cap Boost Pack and the OLED Boost Pack. More will be added in due time including Stacking Headers. MSP430G2553s are on their way too.
 
The store is based off Opencart. It is one of the decent carts out there. Zencart was tried, but it was too clumsy. If anyone needs help setting up their store, I'll be glad to help.
 
Yes, buying the Launchpad from TI is cheaper, but this is just another place you can buy it from. Also, the store only ships to the US. However if you live elsewhere, drop me a pm and I'll see if it can be shipped to you.
 
Just wanted to let you guys know first. It will be announced on the Blog a week later. Any bugs or suggestions,please post here.
 
There are also plans for members to sell their Booster Packs or extensions. Just working on how to go about it.
Thanks!

I don't know about low cost but they all can make 4 layer boards.
 
Try out the cost estimators on the various websites to see what they think it will cost.
 
Alberta Printed Circuits is in my town but there are a zillion board houses out there.

Some of you guys may already be aware of Dave Jones from Australia.
 
He's the guy who does the Elelctronics Enigneering Video Blog
 
Well, a while ago, he put together a tutorial on PCB Design and Layout.
 
Here's a direct link to his tutorial pdf.
 
If you want to make some PCB's and you're a newbie then do yourself a favor and check it out. I'm reading it right now.

Keep in mind that P1.3 has hardware pull-up resistor.

Final.. I will not try to stuff the board to 50x50mm.
 

To me, "exposed copper" means that there is no solder mask covering the pad.
 
In an extreme situation, it could mean that there is absolutely no tinning on those pads as well.
 
The reason for this would be due to mechanical alignment. Imagine the thickness of tinning plus solder. That could create bumps under the module during solder reflow. That would cause the module to float around when the solder is in the liquid/plastic phase transition state. The result is the module moves out of alignment on the footprint. This situation is probably rare and an engineer is just covering his butt with this choice of words.

That should work. :thumbup:
 
Get that on the LaunchPad because you're ready for liftoff.

Oh! I just noticed something else that I would buff. You need a really beefy ground system!
 
On the left side of the board, bottom side, you have a spindley little ground track connecting center ground pour to the left side pins. That will never do.
 
You should make the ground tracks as wide as possible. Say 0.030" and whatever width you can route between the vias. If you can, you should lay down more beefy ground tracks between the center ground pour and the left side ground pins.
 
Try laying horizontally the thickest ground track you can between the center ground plane to the top-left ground pins.
 
Make sense?

:thumbup: :thumbup: :thumbup:
 
That looks perfect to me.
 
One more thing though. I just noticed that the antenna track needs some buffing. It's got to be made into a 50 ohm transmission line.
 
1. Extended the bottom side ground pour so that it is beneath the antenna track.
2. Place ground pours on along the left and the right side of the top side antenna track.
3. Place a hedge of vias along the left and the right side of the top side antenna track.
4. Make those vias connect to the bottom side ground pour.
5. The antenna track width should be 0.010".
6. The spacing between the antenna track and the top side ground pours should be 0.010". This will make a 50 ohm transmission line.
7. Place an approved RF connector footprint at the board edge so you can connect an antenna to the module. I suggest an SMA connector. Either this or this would be fine. It's up to you.
 
 
Is this just a breakout board?

I like the complete bottom side ground flood. That will work well.
 
By the way, is the bottom side ground plane connected to the four pins of the SMA connector using thermal relief pads? Every pad connected to the ground plane should be using the thermal relief pad (for reasons previously noted).
 
I'm having difficulty knowing what is happening on the top side around the antenna track. I can see the vias lined up like a hedge. Are they connected to a top side ground plane as well? They should be.
 
Could you extrude the top side ground plane under the module upwards along the antenna track?
It will then connect the vias to the bottom side ground plane.
 
 
I can see it now. This is going to be an excellent RF clean board. Good work!

Hey, just poking my head in here quick to show off the first prototype of my Zombie in a Can!
 
Check out the VID

 
I used a launchpad with the 2231, a bluesmirf board, a window motor and a custom android app, this thing is awesome! I'm pretty proud that I made this in a night with 2 or 3 broken projects I had sitting around.
 
Let me know what you think! and i'll be posting some scare videos soon
