bluehash 1,581 Posted December 11, 2012 Share Posted December 11, 2012 This is a general call for designing a WiFi BoosterPack based on the CC3000 WiFi chip from TI. There are currently two options available in the market, a LS Research module and Murata. This won't be easy as the designer will have to take into account antenna considerations too. This is a loosely held competition. If we can crowd design this, I can sponsor the first batch of 10 boards and components, probably even the radio(for the first three designers). If it's not feasible, then we drop it.

spirilis 1,265 Posted December 11, 2012 Share Posted December 11, 2012 Antenna wise, it looks like the modules either come with a chip antenna or some kind of RP-SMA connector (I think that's what I spot on the muRata one) -- http://processors.wiki.ti.com/index.php/CC3000_Wi-Fi_for_MCU Quote Link to post Share on other sites
JWoodrell 285 Posted December 12, 2012 Share Posted December 12, 2012 The wifi chip doesnt "come" with either a chip antenna, or the SMA connector, but can be used with either. Digikey has the cc3000 chips for around 25 bucks a piece, (search for "TiWi") and then a 2.4ghz chip antenna is like 7 bucks I am confused as to what kind of design your looking for bluehash, the TI doc SWRU331 you reference shows a schematic and board for a launchpad boosterpack for this already.

(pages 15-18) Not sure yet..This stemmed of a thread which required low power wifi. Unfortunately this one is not. Do you know how much the TI boosterpack goes for? I keep jumping through links and eval kits instead of just getting the booster. Quote Link to post Share on other sites
JWoodrell 285 Posted December 12, 2012 Share Posted December 12, 2012 here is what digikey has for the 3 EM boards (the one shown in the original SWRU331) is around 35 bucks but they don't have them in stock at digikey, the other two are 50 bucks from digikey http://www.digikey.com/scripts/dksearch/dksus.dll?FV=fff40036%2Cfff802bc%2C22c02e8&vendor=0&mnonly=0&newproducts=0&ptm=0&fid=0&quantity=0&PV47=19990&PV47=18777&PV47=18778 the prices are similar at other vendors.

thanhtran 10 Posted December 14, 2012 Share Posted December 14, 2012 This was my quick and dirty break out board. I overcooked the pcb on a cooker and the flux turned brown, but it still works bluehash 1 Quote Link to post Share on other sites

thanhtran 10 Posted December 15, 2012 Share Posted December 15, 2012 Good stuff.. any chance to turn it into a Boosterpack? I have to try the sample code on the F2553 to see if it has enough space first. Quote Link to post Share on other sites
pabigot 355 Posted December 15, 2012 Share Posted December 15, 2012 I have to try the sample code on the F2553 to see if it has enough space first. Code will easily fit but it doesn't have enough data space to do anything useful. Those modules work on the Fraunchpad only because they pull tricks to put the RX and TX buffers into FRAM instead of RAM, and shrink the maximum packet size down to 400 bytes. (Both the G2553 and the FR5739 have 16K "ROM" but with the FR5739 you can use the FRAM "ROM" as RAM.) Quote Link to post Share on other sites
SugarAddict 227 Posted December 15, 2012 Share Posted December 15, 2012 Yeah... I'd sooner throw a 55xx at it, or a Stellaris. Quote Link to post Share on other sites
SugarAddict 227 Posted December 16, 2012 Share Posted December 16, 2012 Like this? No test optional, regular mode only. Didn't bring out uart, RP-SMA connector. Quote Link to post Share on other sites
pabigot 355 Posted December 16, 2012 Share Posted December 16, 2012 Y'know, while I personally wouldn't have a use for a boosterpack for the CC3000, what I would go for is a boosterpack that could take any of the RF Evaluation Modules (including the CC3000 ones) and bring out all their pins. If you could map the basic control pins to the same ones used by the Anaren booster packs, they'd probably be generally useful. For full awesomeness there'd have to be access to all the pins, and some way to re-route them depending on whether they're plugged into a 430 or Stellaris board or used as a standalone breakout. Maybe just an RF-header socket that comes out to two 1x20 0.1" PCB headers for all pins, and solder jumpers continuing on to the boosterpack pins. I believe between the two boards below all the in-use pins for the RF headers can be identified. http://processors.wiki.ti.com/index.php/CC3000_Wi-Fi_EM#RF1_.26_RF2_Interface http://processors.wiki.ti.com/index.php/CC256X_MSP:EXP430F5438#RF1_and_RF2_Connectors Also see http://pabigot.github.com/bsp430/rfem_8h.html#details I have over a dozen RF EM modules in about six flavors and could certainly make use of several such beasts.

How many modules are out there? If their footprints/pinout differ alot, it maybe an issue... not impossible. Quote Link to post Share on other sites
pabigot 355 Posted December 16, 2012 Share Posted December 16, 2012 (edited) How many modules are out there? If their footprints/pinout differ alot, it maybe an issue... not impossible. CC11xx, CC25xx, CC3000, PAN1323. It's the standard form factor for evaluating TI's RF line. They can't vary too much: most of the higher-end experimenter kits support the RF EM interface, and AFAIK only the PAN1323 sometimes requires some extra connections (over RF3). The links I gave cover, to the best of my knowledge, what's necessary: mostly everything uses a SPI interface, and for a few modules there are some additional pins for interrupts, power management, and extra features (mostly for the PAN1323 Bluetooth module). Basically I'm looking for something like http://www.ti.com/tool/soc-bb which I hadn't been aware existed until I was googling to answer your question. I haven't reviewed the schematics for that yet to see whether it covers the PAN1323 and other extensions. So maybe I don't need this, though there might still be a market for it in a boosterpack format. Edited December 16, 2012 by bluehash Fixed broken link. Quote Link to post Share on other sites
