Hi All,

Working on a small project where i want to run an 8x8 Led Matrix with an ESP32. I would like to be able to run it from a Lipo battery when no USB is available.

I have a Charging board with Step up boost converter but i am not sure if how to wire it since i am a noob when it comes to Electronics
If i wire it like this (stepping up the Out to 5v) and plug the usb into the Charging module it works fine as long as the battery has power
as soon as the battery goes out the LED Matrix is doing strange things. I still get 5V but only 100ish milliamps since the battery draws 850ish

Question is if i could use the USB from the ESP and then connect it to the IN pins from the charging port somehow?

Thanks for the link already had a feeling it would be more complicated than just hooking it up and go :)
Once I think I have figured out the loadsharing setup I'll post again to get some feedback :)
