Due to the problem of thinning down the ArOZ Portable, a new LiPo charging and step up PCB is designed and put into the latest thin version of ArOZ Portable. That is a board that with a size only 35mm * 18mm. It uses IP5306 as its core (which is usually used in power bank circuit) and can deliver (and charge) up to 2Amps.

(Sorry for the messy background)
Now I am charging with single LiPo and due to the build in protection circuit, it can only charge at 1.55Amps.

You might have notice that this is the circuit that I used in the latest ultra-thin version of ArOZ Portable and I decided to improve the design so I can use male header to adapt this board to my main board instead of soldering wires to the power circuit. And this is what I came up with :))

For now, I am not sure if it works or not. I will release the Gerber file (and BOM list) after I have tested this. You know, I am a good person and I don't want to lit anyone's house on fire...
