Applications

Ventilator

The function of the ventilator is to allow oxygen to enter the lungs and give off carbon dioxide, helping patients to breathe smoothly. The ventilator connects a tube to the patient's mouth or nose, and the amount of oxygen can be controlled by a monitor.

Based on MindMotion’s microcontroller, the ventilator reference scheme takes MM32F3270 as its main control board and MM32SPIN05PF as the main control of motor:

- As the main control, MM32F3270 is responsible for displaying and communicating with the auxiliary boards such as motors

- MM32SPIN05PF, a motor control board, is responsible for the start, pause and rotation of the motor
