EK-TM4C1294XL: Stacking headers for development board

Part Number: EK-TM4C1294XL

Hi,

This is not directly related to the development board, so feel free to delete if it is out of scope.

For a test and development project, I have a PCB stacked ontop of the EK-TM4C1294XL. Unfortunately, it uses more pins than are available in the booster headers, so im connecting to the 98 pin row instead.

For convenience, I would like to have the possibility to stack additional boards on top or connect jumper wires. So the plan was to solder male pins to the development board, and use female stacking headers on the board that goes on top. Similar to the Raspberry PI stacking headers.

Unfortunately, I am not able to find a female connector for all 98 pins, and it seems that I have to sligthy modify existing female headers (by sanding the edge) to have them directly beside each other.

Anyone know of a part number that matches the 98 pin connector as female stacking header, or multiple of smaller that can be positioned beside each other for 0.1" seperation?

Thanks!

    Great question.   Staff/I do not - yet while 'not ideal' - you may be able to employ 2 or more female stacking headers - by 'sacrificing direct end butting.'   

    This may work for you if:

    • you don't require each/every pin to be carried upward
    • or you can 'tack solder ~24 gauge wire leads' (from the blank pin pair) upward (to an 'out of original pin sequence' location)

    BTW - we've done that (same, unpleasant) header sanding so that we could 'exhaust a large inventory of headers' - no longer used in volume...

    Hello Soren,

    I asked around about this, but we do not have any female header suggestions for that. There is a set of male headers you can get which are the Samtec TSW-149-09-L-S-RE and TSW-149-08-L-S-RA headers - but that's all we are aware of.
