PCB review Portable power supply

[Sagar_Saini]

I have designed this power supply unit to get 3.3, 5, 8 and 12V. So that it acts like a secondry supply to test and power small projects and mircocontroller.

1. I used TP5100 as charging in 2S mode

2. 5v boost up mt3608 charging to charge the battery direclty from usb_5v

3. Then some linear regulators for 3.3 and 5v

4. And again a mt3608 booster for 12V out

I may utilize same booster circuit for charging the battery and 12V but then I have to change the jumpers and all, which I don’t want. I have shared the scheamtics as a another fourm post.

It’s also not a kicad project, so why post on the KiCad forum? It should be easy to convert it to KiCad though. KiCad does have an import for EasyEDA, but I have not tried it myself.
