Since the outbreak of COVID-19 in 2019, many existing life and work patterns have been changed. This makes smart monitoring and other products that have been on the market for many years to become mainstream applications again. And with the continuous innovation of 5G, Internet of Things and other technologies, smart monitoring products have been given more functions, such as remote video conferencing, smart city monitoring, home monitoring, newborn and nursing home care applications, etc. The emergence of these innovative monitoring products has opened up a new model for people to communicate and work remotely. Based on TOSHIBA M342/M343 MCU, the intelligent monitoring and remote video solution launched by Dalian Da Shiping has low cost and high flexibility, and can be easily applied in various scenarios, thus reducing the development time of customers.

TOSHIBA M342/M343 MCU is based on Arm Cortex-M3 processor architecture, with built-in multiple sets of H-Bridge and mirco-stepping drivers, which can make the product widely used in motor control, intelligent monitoring, remote video, Internet of things equipment, home appliance equipment etc. in the scene. And because multiple drivers are integrated in the MCU, the PCB size can be further reduced, and the system development cost can be reduced.
