Started with PCB Design. Planning to go with a 4 layer pcb but might instead switch to a 2 layer one. Trying to conserve space and make it as modular as possible.
Schematic and Footprint Finalization:
I started by finishing the schematic for the esp32 and making sure that everything was proper it to work. Using the advice of many people online, I added capacitors that would help the latency issues that might arise. I spent a lot of time also on the footprints so that finding the parts and ordering them would not be a problem.
I started out by designing all of the battery schematics. I used several different sources online in order to figure our how I should get this set up and how to make sure it works how I need. The following two sources were invaluable resources in figuring out how to use the battery monitor to set this up. Combining this with a P-Channel MOSFET, I am able to separate the power delivered to the esp32 with either usb or LiPo battery. I haven’t set up all of the schematics nor components needed to make a proper/working ESP32 but that will be what I complete next. https://how2electronics.com/lithium-ion-battery-charger-circuit-using-mcp73831/
