Battery Charger & Protection & Boost 5V or 12V

$2/5pcs 2Layer & $5/5pcs 4Layer PCBs: https://jlcpcb.com 🔥I always use a 3.7V battery charger module and then I add a boost converter to get the 5V for my Arduino and so on. I wanted to have everything on the same PCB so I've used the protection ICs, charging and boost ICs and like that I have all I want on the same PCB. Hope you like it.
