STM32L4R9I-Disco MB1314C MIPI Connector

Hello,

I would like to replace LCD Screen on the STM32L4R9I-Disco MB1314C board with another one.

As explain in board datasheet (UM2271) the display screen (reference IEG1120TB103GF-001) from Govisionox Optoelectronics use a molex connector 504248-2410.

The mating connector specified in both LCD datasheet and STM32L4R9I-Disco Bill Of Materials is 504208-2410(Molex)

I purchased the following 400x400 LCD Round screen which have the same Molex connector (has specified in datasheet) but in fact this one does not fit in MB1314C board.

To validate that the error does not came from the new screen datasheet i purchased some Molex 504208-2410 connector from Mouser. These connector fit with the 400x400 LCD Round screen.

I can confirm that both LCD datasheet and STM32L4R9I-Disco Bill Of Materials is wrong about this connector but i need to know which reference has been used for connector CN2 on MB1314C by STMicroelectronics to be able to adapt my other screen to the discovery board.

Thanks

Simon

Hello STrop,

Sorry for the long delay, just detected your post today.

I found out the MB1314C integrates a new connector reference. CN2 part number was changed into BM20B(0.8)-24DS-0.4V(51) from Hirose.

Best Regards
