Regarding STM32H753I-EVAL2 board

We are using STM32H753I-EVAL2 evaluation board. We need to test SPI functionality of microcontroller. The board gives a provision to use CN6 & CN7 connector to do this. But the Samtec connector couldn't be connected with any jumping wires nor we could find a mating connector. How to use these connector pins to test SPI functionality?

    Hello @AkshayMR ,

    They are called hook clips:

    You need to find the smallest one to fit the EVAL board connector and prevent any short circuit between the pins.

    But as said by @Andrew Neil , it's preferable to use Nucleo board with 0,1 inch pitch (2.54mm) connector.

    Use this kind of connectors:

    What are these connectors called?

    An image search will find them from the picture; eg,

    But you'd still be stuck with the fact that the EVAL port uses-up the pins with all those "extras"

    Therefore I'd still recommend a Nucleo board for unencumbered access to the microcontroller's pins.

      The User Manual gives the Samtec part number:

      https://www.samtec.com/products/ftr-130-03-l-d-lc - offers a free sample, and has a link to Mouser to purchase.

       

      Or, for easy access to the microcontroller pins without all the extras of the EVAL board, maybe a Nucleo would be more appropriate?

      They have simple 0.1" headers ...
