 Arduino Lab for MicroPython is an [Electron](https://www.electronjs.org/) app that has its main purpose to communicate over serial with a microprocessor running [MicroPython](https://micropython.org/). All Electron code is at `/index.js`.
 
-All operations over serial are abstracted and packaged on `/micropython.js` which is an attempt of porting `pyboard.py`. The port has its [own repository](https://github.com/murilopolese/micropython.js) but for the sake of simplicity and transparency, `micropython.js` is committed as source code.
