Trải qua trên 35 năm nhiều tiến bộ khoa học kỹ thuật ứng dụng công nghệ thông tin trong thiết kế. Với các nước tiên tiến, thường đại học là nơi đi đầu trong việc giới thiệu, chuyển giao những thành tựu mới nhất về kỹ thuật thì đáng buồn thay lại đi chậm so với thực tế ngoài đời. Trong lĩnh vực vi xử lý, vi điều khiển rất nhiều thế hệ chip mới ra đời có giá thành rẻ cùng tính năng kỹ thuật nổi trội nhưng chưa được đưa vào giảng dạy, ít nhiều ảnh hưởng tới việc làm của các kỹ sư mới ra trường.

Descriptions: The module is a portable power bank that supports two voltage outputs of 3V/1A and 5V/2.2A. The rated current of 5V voltage output is 2.2A, and the maximum support current is 3A (not recommended for overload, easy to damage the module, and accelerate the service life). The output of the current depends on the quality of the battery. Micro USB has a charging current of 600mA-800mA and supports up to two batteries. It is recommended to use two batteries, which can be longer. When the switch is turned to NOMAL, the current output is lower than 30ma, and it will automatically stop in about 10 seconds and switch to standby mode. When it is toggled to HOLD, no matter what happens, it will remain on until the battery is dead (the 2512 resistor on the back will heat up). Special Attention: The battery must be installed with positive and negative poles. The positive and negative poles are clearly marked on the board, and incorrect installation will burn the module.
