I was trying to connect a VNH2SP30 content.solarbotics.com/products … ry-gm8.pdf. When I connected the battery to the motor driver, the red LED flashed erratically for a little over a second then stopped, the battery felt very warm, and there was a slight burning smell before I could get the battery disconnected.
I don’t know if I used the wrong power or if I wired it wrong. I followed the diagram in this post Dual VNH2SP30 MD03A with Arduino: Programming, PWM issues, and afterwards I double checked that the VIN and GND were correct and all the batteries in the holder were in the right directions.
I used 3 Li-ion AA batteries with 3.2V 400mAh each. I thought the voltage would be 9.6, and it would be ok for the driver and the motors. I haven’t added the 2 capacitors that came with the board because I thought they were just for interference and I could add them later.
Does it sound like the problem was with the wrong kind of battery, bad wiring, or something else? Is there a way I can fix my motor driver?
Thanks for any help. I really appreciate it.
