Connector choice for STM32 based robot controller using an STM32F4 series board

[loveforcircuits]

I am working on an STM32 based robot controller using an STM32F4 series board. The system includes IMU, encoders, and multiple sensor modules. During vibration and movement, some jumper connections become unreliable. I am currently using standard Dupont wires for prototyping. However, repeated disconnects are causing unstable sensor readings. I want to move to more robust connector solutions for PCB to wire interfaces.
I am confused about which connector types are best for pin based headers. Should I use JST, Molex, or locking header connectors instead of Dupont? What connector systems are commonly used in STM32 embedded designs?
I also need something suitable for frequent assembly and maintenance.

Indeed, the so-called "dupont"-style flying leads are notoriously unreliable!

I suspect that most things sold as "dupont" are not actually made by DuPont...

This really has nothing specifically to do with STM32 - it's just standard design for any electrical connections.

I suggest you look at what is used in similar commercial designs.

Try searching distributor catalogues for connectors designed for high-vibration environments.

You probably want connectors with some sort of latching mechanism.

Yes, JST & Molex are well-known manufacturers with wide ranges of connector products - I'm sure they will have something.
