Expand EK-LM4F120XL with CC3100 and LCD sharp96 boosters

Other Parts Discussed in Thread: CC3100BOOST, CC3100

Hello,

I bought this evaluation board: TEXAS INSTRUMENTS EK-LM4F120XL

Now, I want to expand it and I think that I can connect it with these 3 boards:

 - TEXAS INSTRUMENTS CC3100BOOST

 - ELEMENT14 BOOSTXL-BATTPACK

 - TEXAS INSTRUMENTS 430BOOST-SHARP96

 

Could you confirm that is possible to stack all 4 boards?

Thank you very much.

    Most likely you can stack the CC3100 boosterpack and Fuel Tank Booster Pack, as from what I know both are designed to current booster pack standards.

    This however from what I know cannot be stacked at those two booster packs above. 

    To be sure that these three booster packs can be stacked, checked the pin connections at the User's Guide.

    If you look at the schematic for GPIO pin (J1, J2, J3, J4) and other boards, you can stack two boards on EK-LM4F120XL or preferably expand them on auxiliary board, but make sure you correctly correspond VCC, GND and control signals to other board.

    Do note that your EK-LX4F120 has joined "dinosaur crue" - no longer walk this planet.  May be better to "invest" in newer boards - w/supported devices. 

    I'd be concerned about the power management with potentially "excessive" stacking of such boards.  May be prudent to construct a power budget for each board - and determine if your power source is adequate. 

    And note - should your boards (even some of them) be powered individually - your power sequencing may require attention...

    EK-LX4F120 it may be old but this is what I already have; it fits for one application.

    I will be prudent regarding the power source. First off all, I hope that I can use the Fuel Tank BoosterPack. If not, I already have the option of mains power. I know that the CC3100 need special attention. I remember that it can consume up to 400mA!

    ""dinosaur crue" - no longer walk this planet"  Good one.

    Thanks for the tips.

    Hi. Thanks for the tips.

    These are the pins for CC3100 booster pack:

    And these are for the LCD sharp96:

    I would say that will work, since the VCC and GND are correct. Just need to be careful for the enable pin and how to handle the SPI.
