Serial Usb - Pycom WiPy 3.0 Manual

1.3.4.1 Serial USB
Serial USB REPL (UART)
To use the REPL, a Pycom device must be connected to the host computer with a USB
connection either to an Expansion Board or to serial converter (a diagram of how to do this
can be found the the getting started page for your module).
In order to connect to the REPL over USB serial, there are multiple methods. Detailed below
are the explanations of how to do it in MacOS, Linux and Windows.
All platforms
By far the easiest way to access the USB UART REPL is via the our Pymakr plug-in for
Atom and Visual Studio Code. This adds a pane to the bottom of the editors that allows you
to directly access the REPL and any output from the device. Detailed instructions on how to
setup Pymakr can be found here.
