IWR6843AOPEVM: Questions about IWR6843AOPEVM and MMWAVEICBOOST

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: MMWAVEICBOOST,

Hi!

Thanks for taking time to look into my question!

1)

I am trying to make a 60pin HD connector board myself to gain access to more signals on the IWR6743AOPEVM.

But it seems that the stick in the circule below is blocking the way.

Is it ok to remove the pin or shift the position of the pin such that it won't conflict with the connector board?

2)

By the way, I accidentally connect a 19v power supply to MMWAVEICBOOST, it seems that it is burnt now, is there any way to repaire the board?

    sorry for the typo in the first question, it should be IWR6843AOPEVM not IWR6743AOPEVM

    Hello Piao DENG,

    1)    This pin is provided to mount the 60 pin HD connector correctly in one direction to MMWAVEICBOOST board. 

    This pin is not connected to any functional signal in the design.  

    If you remove this pin there is a chance that wrong 60pin connector could be connected from the MMWAVEICBOOST BOARD, which might damage both the boards.

    2) If there is high voltage is connected to MMWAVEICBOOST, there could be several components could have damaged, It's hard to isolate and assess the extent of the damage. it's better to get a new board. 

    Thanks and regards,
