Still have some work to do on this - will post CAD files later. oPossum, Very nice job! i would add, though, the little weird port that the Launchpad has next to the headers right-top hand side, that port is so that you can plug in eZMSP_2500 or the eZMSP_2650 wireless boards, or just the emulator Stick, on the launch pad the eZ-FET also doubles as a serial port which in this case we are loosing it all together, i know we do not need a comunication port all the time, but would be a nice feature to have should you need one (the little weird port that is) And one more thing, i would call it "Launchpad-PRO" although i am not sure if "Launchpad" is a trademark from TI, well we'll see... regards Luis Quote Link to post Share on other sites
nuetron 64 Posted December 28, 2011 Share Posted December 28, 2011 Hey oPossum, just wanted to let you know that the reset button in the upper right section of the pic is only connected to gnd, without a track to the reset pin. Quote Link to post Share on other sites
oPossum 1,083 Posted December 29, 2011 Author Share Posted December 29, 2011 First post updated with Eagle files. I will probably order 10 of these in about a week. Quote Link to post Share on other sites
MattTheGeek 99 Posted December 30, 2011 Share Posted December 30, 2011 I thought i'd give it a try. Silkscreen and final part placement/adjustments still need to be made. Also added a reverse polarity diode, and PTHs for through hole crystals. 1206 components should be as easy to solder as through hole. I'm also considering making the programming connector 1.27mm so it can be programmed by the LP or Ez430. Quote Link to post Share on other sites
zeke 693 Posted December 30, 2011 Share Posted December 30, 2011 Looking at all these pcbs gives me an idea. I think we should start in informal contest to see how much circuit we could design into a 50mmx50mm pcb. Thoughts or reactions? Quote Link to post Share on other sites
turd 31 Posted December 30, 2011 Share Posted December 30, 2011 I'm also considering making the programming connector 1.27mm so it can be programmed by the LP or Ez430. You could put them closer to the edge of the board in front (and addition to) the .1" ones you have. Quote Link to post Share on other sites
bluehash 1,581 Posted December 31, 2011 Share Posted December 31, 2011 First post updated with Eagle files. I will probably order 10 of these in about a week. I can put this under the $10 Sponsorship. If you want, $10 is yours. Put a [RFS] tag in the title of your first post and I'll move it to the BP section. Quote Link to post Share on other sites
cubeberg 540 Posted January 2, 2012 Share Posted January 2, 2012 I could totally go for a set of these! Do you have a BOM for the other parts? I'd be interested to see how the price of parts falls in comparison the LP's $4.30. Quote Link to post Share on other sites
pfactorial 7 Posted January 3, 2012 Share Posted January 3, 2012 Is it possible to make it single sided? Quote Link to post Share on other sites
MattTheGeek 99 Posted January 4, 2012 Share Posted January 4, 2012 Is it possible to make it single sided? I'm pretty sure it can be done. Quote Link to post Share on other sites
cubeberg 540 Posted January 5, 2012 Share Posted January 5, 2012 Anybody find any errors? I'm planning on ordering my own set of 10, but I wasn't sure I wanted to be the first one Quote Link to post Share on other sites

cubeberg 540 Posted January 6, 2012 Share Posted January 6, 2012 I mostly mean out of pocket for myself. I figure about $15 for the boards. I've got the headers, 430's, LEDs and resistors on hand. The only thing I really need to buy are the capacitors and switches. I priced the parts out at a site I've bought a lot of other stuff at - http://www.taydaelectronics.com and it's about $4 in parts and their shipping is cheap. That'd put me under $30 for 10, even if I bought extra parts from Tayda. Quote Link to post Share on other sites
