Recently TPYBoard v202:
The following is used micropython Developed led routine , Board connection wifi And then get Ip Address , And print it on the serial port , adopt ip Address use browser to access the page , Achieve control led switch :
effect :
I made a slight change in the official routine , Removed login page , Beautify the control page :
because esp8266 The built-in memory is too small , One time open device.html Not too big , Otherwise, incomplete web page files will appear , Web pages cannot be displayed on the mobile phone , So we must pay attention to this .

python It is also suitable for raspberry pie with high performance , Not suitable for MCU, although MicroPython Than Arduino Stronger , But the running performance is not as good as Arduino
