EK-TM4C123GXL: Adapting the Tiva Launchpad to a breadboard

Part Number: EK-TM4C123GXL

Perhaps I'm overlooking something obvious but I can't plug my Launchpad into a common breadboard without shorting pins out to each other. I was wondering how others dealt with this very annoying problem of having a floating kit flopping around all over the place. I'm surprised they designed it this way and keep thinking I must be missing something. Is there a product to anchor it onto a board ?

  • Hi Charles,

      Please refer to the EK-TM4C123GXL LaunchPad user's guide for detail. https://www.ti.com/lit/spmu296

      Look at the J1, J2, J3 and J4 connectors for the pins that are provided. Let's look at the J2 connector for a moment. The first pin on J2 is GND. There are other GPIO pins on J2 such as PB2, PE0, PF0 and etc. Suppose you drive PF0 to high and depending how you orient the LaunchPad board on your breadboard, you will immediately short PF0 (driven high) to GND. That may be what you are seeing. You can blue-wire between the LP and the breadboard or you will need to create a custom breadboard. There are various BootsterPack boards that you can attach to the EK-TM4C123GXL board for evaluation. Please look at this BoosterPack website. https://dev.ti.com/bpchecker/#/
