STM32H743EVAL2 Pin extension

[Hamxa10]

hi guys,

I hope this message finds you well.

I am currently working with the STM32H743Eval2 evaluation board, and I'm facing a challenge with the smaller pins on the board. Specifically, I've noticed that the standard-sized pins do not fit in these smaller pin slots. how can I reach these pins.

Thank you very much for your time and assistance.

Perhaps pull the BoM from the "CAD Resources" tab on the product page. Determine the header type and pitch from the BoM

Hello,

Internally we have a such adapters to access that connectors on H7/F7 Eval boards:

 

But unfortunately they are not available on the market :frowning_face:. 

I would suggest:

1- The usage of that kind of "clips" (I don't know if this is the right naming) that you can attach directly to the pin:

 

2- Solder wires on the connector pins base if you're familiar with soldering.
