RobG 1,892 Posted October 19, 2012 Share Posted October 19, 2012 EDIT: The newest Ethernet BP v3 is here Thinking about a new version of the Ethernet Booster Pack.What's different? All parts will be on top layer (I might keep few on the bottom,) removed opto, LDO, and MCU socket.New on the board is serial SRAM, which could be used for things that require more RAM, like DHCP client.Other possible changes: different MagJack, smaller board, high current driver.Any suggestions?

Nytblade 24 Posted October 20, 2012 Share Posted October 20, 2012 One thing I don't understand is how the boosterpacks are supposed to stack on top of one another. On the Anaren boosterpacks they have a second level of pins, which makes sense, but none of the others have that. My question is: let's assume that I have the ethernet BP on my Launchpad, how do I add another boosterpack? (let's say the SD card reader one). The first boosterpack blocks access to all the pins. Is there a way to stack them... some headers with gigantic passthru pins or something? (I am sure this a total newbie question, lol) If there is a way to stack multiple boosterpacks, then I'd say, go for minimal features, just ethernet+sram only. Otherwise you may want to make different flavors of Ethernet boosterpacks with different secondary functionality... Quote Link to post Share on other sites
RobG 1,892 Posted October 20, 2012 Author Share Posted October 20, 2012 You can use stacking headers, but the height of the components (MagJack in this example) might be the issue here. CS lines are another problem, but that can be solved by giving user an option to select two different pins on the BP. Personally, I am not a big fan of stacking headers or stacking BPs.

I dunno, I guess this would not be a problem on the C2000, due to it's male pins on the bottom. Just difficult with the MSP430 Launchpad. I'm trying to figure out a way to make the ethernet useful for any type of project that might need it. E.g. if I want to use it with a sensor... it is hard to get at the pins on the MSP430 LP.

Nytblade 24 Posted October 21, 2012 Share Posted October 21, 2012 What exactly do you mean, BTW, when you say "high current driver" ? I don't know what that is. Could that be used as a switch for an AC Lamp? Quote Link to post Share on other sites
RobG 1,892 Posted October 22, 2012 Author Share Posted October 22, 2012 Done with the layout, it should be a lot easier to assemble now. What exactly do you mean, BTW, when you say "high current driver" ? I don't know what that is. Could that be used as a switch for an AC Lamp? I was thinking low voltage, up to 500mA driver, but I have decided not to include one. For AC, you can use Dual Triac board. Quote Link to post Share on other sites

Nytblade 24 Posted January 11, 2013 Share Posted January 11, 2013 Could you tell me the SRAM pinout? I assume it is a microchip SRAM? I don't think it would be needed for spirilis's Launchpad but I'm curious anyway. This below is for my own reference... (I see it is the same as your first board which I already have) Wiznet Pinout MOSI - 1.7 - G2553 UCB0SIMO MISO - 1.6 - G2553 UCB0SOMI SCLK - 1.5 - G2553 UCB0CLK SS - 1.0 - G2553 gpio INT - 1.3 - G2553 various or 2.7 - G2553 xtal out or *NC PWDN - 2.0 - G2553 gpio / timer or *GND RST - 2.6 - G2553 xtal in or *1.4 - G2553 various Quote Link to post Share on other sites
