I’m running a robot driven by a VNH5019 dual motor driver, two 25D gearmotors, and a 7.2V NiMH battery pack. My microcontroller and sensors share this same battery rail via a 5V buck regulator.
Under sudden acceleration or single-motor pivot turns, my BNO085 IMU would lock up and stop sending data (likely due to voltage dips from motor current spikes). To fix this, I soldered a 2200 µF electrolytic capacitor directly into the motor driver’s auxiliary capacitor holes.
I wanted to double-check: is adding a capacitor of this size directly to the driver board a reliable long-term solution for this setup, or are there any drawbacks I should keep in mind?
