This is a simple powerbank with a powerful led and ATtiny202

Timeline

I finished the PCB. I had to change/rewire a few components, but it should be finished! Now time to do the case

I started placing the components for the PCB. I started with the Powerbank IC

Today I started with searching an IC that I could use for the powerbank. I wanted a USB PD cabable one, but they were quite a bit harder to use, more expensive, and needed multiple cells, so I ended up with a 1S 5V/3A powerbank. it will be enough to fast charge a phone. And I will also be able to use the voltage to power the led easily, as it is always on.
I went with the ATtiny202, BQ25895 and AL8860MP ICs.
I finished the schematic with all the components. Hope it works
