1. Based on STM32 do open source products. Oscilloscope and a multimeter.
2. The good helper in measurement and maintenance work.
3. Can be used as a good tool for STM32 series MCU programming. 

Outdoor Maintenance(AC/DC Power and Inverters, floor fire equippment and circuit-control).
Hardware maintenance and software debugging RS232/RS485/I2C/CAN and so on circuit, LED display and scanning driver circuit via keyboard
Audio device and circuit, elecrtic toys and remote models, car circuit maintenance.
School tutoring and DIY electronic-development.
Somewhere needs to observe the slow signal changes (eg. Relay module and inch-switch, battery charge and discharge curve, temperature sensor measure and so on.)
Power for related circuit.
