Im trying to learn robotics with raspberrypi but im having a problem. I have 6 AA batteries that are connected to a LM2596S adjustable voltage regulator module, Which then is connected to the raspberryPi. I turned down the V provided to about 5V, but as fast as I provide power to the Pi it drops down to about 4V which is not enough power for the pi to run and makes it shut down. I have tried adjusting the power (out) to 6,7V but the same thing keeps happening when I connect it to the Pi, the V (out) drops down to 4V. The V (IN to the module) shows about 8.2V when not connected to the pi, but drops down aswell as soon as I connect it. What hardware is most likely damaged here and what should I try?
The Pi runs perfectly fine when connected to a power adapter.
