ESPbreakout is a breakout board for the popular ESP32-s3 chip that includes many breakout pins, compatible with any other ESP32 setup (for the most part), and has programming via USB 2.0. This board uses the ESP32-S3 SOC, which means that it does not use any of the modules that espressif has already made, and just the bare ESP32-S3 chip. This board includes pins for progamming, a USB-C port (for programming & power), a screw terminal to convenient wire up a Lithium battery to (3.7v). And you can also utilize the PSRAM that I added externally onto the board. The board includes comprehensive labels for buttons and pins, for ease of use. The cost and materials used to manafacture/make this board are in the BOM.csv file.ile.e.
I made this board to showcase what I already know, and to learn a lot of new things (I can say that this one was accomplished). I also made this board to act as a substitute for the ESP32-S3 devboard that exists, and of course it wont be better than the board made by the actual company, Espressif, but it will be pretty decent and working!
