oPossum 1,083 Posted November 12, 2011 Share Posted November 12, 2011 Here is a crazy idea I had - looking for feedback. This is a small development board that can use up to three Launchpad Boosters concurrently. It has nine 1 x 10 pin headers. Two are on the bottom, and carry the same signals as two on the top. A 1 x 6 pin header is used for program/debug and power. (click images to make scroll bars go away) The "Flying Solo" single booster configuration. The headers surrounding the booster board allow access to I/O lines not used by the booster. The "Flip Board" configuration. One booster is on top of the dev board (green) and the other in on the bottom (blue). The "Trifecta" configuration. An extender board is used to allow for a third booster. It may be possible to use some boosters without the extender. The "Two Boards at Once" configuration. Trifecta without a bottom. PentiumPC 1 Quote Link to post Share on other sites
PentiumPC 119 Posted November 13, 2011 Share Posted November 13, 2011 That is a great idea. I actually wanted to make a dev board that can carry 2 boosters based on 5529 or something. But making a board for the 5529 might be beyond my skill level now. Your idea is very interesting with many configurations, If you don't mind, here is my rough idea and suggestion. 2 standard booster slots, should be enough since we can still stack the boards with long stackers. Some pins or the rest of the pins broken out into non standard double or triple row headers. or 1 standard booster slot + 1 Arduino compatible slot. (haha, don't flame me) Some pins or the rest of the pins broken out into non standard double or triple row headers. Cheers, Terence Quote Link to post Share on other sites
bluehash 1,581 Posted November 13, 2011 Share Posted November 13, 2011 Love it oPossum.. Question: - Will the pinout be the standard BP pinout? Considering they are all broken out from one chip. Quote Link to post Share on other sites
oPossum 1,083 Posted November 14, 2011 Author Share Posted November 14, 2011 It would be the same general pinout. The LP has power, reset, test, P1 and P2 on the 20 pins. The Flip Board would have... Top Board: power, reset, test, P3 and P4 Bottom Board: power, reset, P1 and P2 Side Board: power, reset, P5 and P8 XT1 and XT2 do not share any pins with any boards, so both LF and HF crystals could be used without sacrifice of any GPIO.

TopHatHacker 25 Posted November 16, 2011 Share Posted November 16, 2011 i really like the idea... just hard to implement right now... we don't have as set-in-stone of a booster layout as arduino has shield layouts.. I'd like to see some more boosters come out, and what people come up with Quote Link to post Share on other sites
