【Training Camp】Jialichuang Robot Dog

Introduction: This is my first time participating in Lichuang’s training camp program. I feel that I have learned a lot and will continue to do so if I have the opportunity in the future.
I am also grateful to Lichuang for the free board making and component coupons. The first time I made the board, there were some problems that caused a MOS tube to explode because I did not check it. Later, after improvements, I made a new board.
