#The 7th Lichuang Electric Competition# Ammeter - Development Board

Introduction: This is my first time to attend the training camp.
The experience is really good (dog head.PNG). Since I am a newbie, I followed the training camp to draw a board, but I found that only a few N32 IO ports were used. Based on the principle of "a friend dies rather than a poor Taoist" (the principle of freeloading), I combined it with the development board and squeezed every IO port.
