Application:
- 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.
