Project Summary:

This project was designed and executed by Qmax for a US customer. It is used to control the actions of a mannequin used for training doctors. The system uses the powerful Qualcomm Snapdragon 820 Chipset. The unit can be POE powered and works as POE injector switch. Multiple similar units can be interconnected through LAN to perform specific functions. The system also has a K66 MCU which runs RTOS to control specific real time functions.
