Hi everyone so this is actually my first post and please forgive my ignorance, I'm 16 and I'm working on a prototype I've finished the majority of it but now I need to make it tick ( I need a circuit) so this is what I need a small circuit that can fit in a 58mm x 33mm x 10mm LxWxH area
the circuit will have to regulate a current that will vary between 2-3.7v and be able to safely charge a 3.7v battery ( **broken link removed** ) and show the battery life with 4 0805 smd leds, have an or off switch for charging, usb input for charging the battery ( along with what i mentioned before about the irregular current 2-3.7 v) and lastly output to a lightning connection. Thanks for any feedback and again sorry for being ignorant if I was but I need a schematic made for this so I can make the pcb, pay $20 if somone wants to make the schematic. pm me for details if you're interested thanks.
