# W55RP20-EVB-PICO simple server example
#
# To test, you can use your webbrowser
# you have to find out the ip-address of the board first ( should be printed in the Micropython console on startup )
#
# example: http://192.168.178.48/

# !! Use it at you own risk, no warraties, only for test purposes, no security implemented !!
