Prototyping the ADX Core v0: Solving the MTE210-24RL Dimension Mystery

I am currently prototyping ADX Core Version 0. While working on the enclosure design and verifying dimensions, I hit a roadblock with one specific component: the MTE210-24RL IDC terminal.

The Missing Data Challenge

While reviewing the official datasheet for the MTE210-24RL to finalize the mounting points, I noticed a critical oversight—the dimensions for the screw holes were completely missing. Without these specs, it’s impossible to guarantee a perfect fit for the enclosure's mounting boss or ensure proper PCB alignment.

Taking Matters into My Own Hands

To keep the project moving, I went back to the physical hardware used in our previous prototype. Armed with a pair of vernier calipers, I took manual measurements of the terminal. Based on the readings, it appears the holes are designed for M2.5 screws.

I’ve since updated the EasyEDA 3D model to include these through-holes. However, I still have a slight hunch that there might be a discrepancy between the other datasheet values and my manual measurements.

The Path Forward: Iterative Prototyping

In the world of hardware development, documentation doesn't always tell the whole story. Given the uncertainty regarding the exact clearance, I’ve decided to proceed with these measured values and refine them through the prototyping phase.

Trial and error is often the fastest way to verify physical tolerances, so we’ll see how the next print fits. Stay tuned to find out if the M2.5 assumption holds up!
