pwm dimming small light (verified)

Overview

Creative small lamp, you can replace LEDs within 2a/30v, with pwm dimming (it is recommended to add a potentiometer with a switch)
TypeC requires extra shipping cost, so I added two solder pads because I was too lazy to replace them. You can remove
the potentiometer and choose the best one . It's cheap. I don't know why the dimming is not obvious (can you comment on it?). The multimeter has tested the pwm ic and there is a voltage difference. It should be adjustable.
If you want to use lithium batteries, you need to add a boost chip and a power management chip. Just If you want lights, you can remove the potentiometer and pwm. The effect is not obvious and it is a waste of money.

HR asked me to go back and look at ARM, which operating system should I choose?
I just signed a job. HR told me to go back and look at ARM. I have never used it before. I am so confused. Which operating system should I use?
