Hello, I am working on a portable retro game console and am trying to get the battery circuit working. I am powering the circuit with a 3.7v 4500mAh lipo battery, so I wanted to use a boost converter to boost the voltage up to 5v so I could power all of my components. Here is the converter I purchased: https://www.amazon.com/dp/B06XRN7NFQ/ref=cm_sw_r_cp_api_glt_fabc_TJTXY59JSCW61ASRQJYB
It had good reviews and it said it could boost voltage up to 35v which was more than enough for my project. Unfortunately, when I got it and plugged in my battery, adjusting the potentiometer did not have an effect. After multiple counter clockwise turns I was able to get the voltage down to 1.2v, but once I boosted up to around 3.3v it would take a lot of clockwise rotations to even boost it up to 3.5v, and I couldn’t get it to go any higher. Is there something I’m doing wrong? Is my bird faulty? Should I purchase a different board?
Thanks in advance for the help.
