Z Looking Glass: Project SmartSurfaces

A insider's observation of Project SmartSurface

FedEx-Crushed Pololu Motor Controllers December 19, 2009

Filed under: Uncategorized — zilinzen @ 3:58 pm

Everyone was quite excited when the motor controllers we ordered came in today. However, what we saw in the package is quite disappointing.

All the capacitors that are supposed to go on Dual VNH2SP30 Motor Driver Carrier MD03A board were crushed. The boards looked okay but we are not sure if they were damage as well since there was no way to tell until we test them. However, looking from the side, one of the dual boards (we order two of them) was clearly deformed (see pic below). Again, I’m no expert in circuit so I don’t know if the embedded circuit is damaged or not. All I can do now is finishing reading the long datasheet and figure out a way to wire the motor controller to Arduino Mega without frying neither of them. I talked to John and he is working on convincing the vendor to replace the capacitors. At the mean time, Eric is looking for the same type of capacitors in Ann Arbor local electronic stores. The Pololu High-Power Motor Driver 18v15 appeared to be intact, but only the board. Some of its capacitors are panned too.
