Open-Smartwatch KiCAD files, Electro707's Fork

Repo Electro707's fork of the Open-Smartwatch project. You should be in the e707 branch.

My Changes

Here are some changes that I plan on doing to this design:

• Replace the battery charger and power mux combo with an integrated PowerPath TI charger IC (BQ24230RGT)
• Replace the module with an ESP32-PICO-MINI-02
• Replace the connector with a TypeC
• Replace the RTC with a smaller package one (RV-8523-C3)
• Added a 3D compass/accelerometer/gyroscope IC
• Added a temperature/humidity/pressure sensor (BME280)

Tools

To view/modify the files from this repository, install KiCAD from: https://kicad.org. Must use the nightly version of KiCAD, bonus points if you build it from source

Also, add the following Symbol/Footprint library to KiCAD: https://github.com/Open-Smartwatch/Kicad-Libraries

Schematic (May not be updated to this version)

Plots (May not be updated to this version)
