I Upgrade my Esp32-cam

if you have ever worked with eap32cam, you know even for thebasic needs like uploading the code, there is lot of wiring

so like every other engineer which facing difficulty, Ishould solve this problem

which starts with designing a shield for esp32cam

after a few months, I came up with this design, which allowus to

• uploading codes without pain and unnecessary wiring
• charging batteries
• easy access to all the gpio
• and other features like separated i2c connection for OLEDdisplay and a neopixel led

for the USB to TTL circuit which is able to upload the codedirectly to the esp32 chip. I used cp2102 also I could use a ch340 chip but forthis project, I was looking for quality rather than a good price.

part of this project is charging the battery, so for thispart, I used tp4056.

usually, you seen this chip on the battery charger module
