REPL
F1 smart module pre-installed MicroPython as operating system (OS), which equips with REPL. REPL stands for Read-Eval-Print Loop which is an Interactive Interpreter Mode that allows you to input code, execute it, and immediately see the results.
Open and connect a device or use serial terminal (PuTTY, screen, picocom, etc) with the CtrlR Plugin. Upon connecting, there should be a blank screen with a flashing cursor. Press Enter and a MicroPython prompt should appear, i.e. >>>. That’s where the commands go.
