DOMini: A Versatile Digital Oscilloscope for Diverse Applications

The DOMini digital oscilloscope is a powerful tool perfectly suited for students, hobbyists (especially Arduino users), researchers, and electronic engineers. Its comprehensive features make it adaptable to a wide range of tasks.

Key Features:

• Six measurement channels (four analog + two digital).
• Four measurement modes: single, normal (standby), auto, and recorder.
• Triggering based on event occurrence for precise data capture.
• Real-time Fourier analysis for frequency domain insights.
• Extensive waveform memory: 13,200 measurements for analog channels (up to 26,400 for the logic analyzer).
• High sampling rates: 5,000 to 1,000,000 samples per second for analog channels; 5,000 to 12,000,000 samples per second for digital channels.
• Multiple voltage options: +3.3V and +5V power supply.
• Probe calibration with customizable units.
• Compatibility with standard x1 and x10 oscilloscope probes.
• Wide voltage measurement range: ±5V, 0-10V (±15V, 0-30V with x1 probe).
• 10-bit resolution Analog-to-Digital Converter (ADC).
• Four digital PWM inputs/outputs.
• Comprehensive digital interfaces: SPI, I2C, UART, and 1-WIRE.

Applications:

• Comprehensive analysis of analog and digital signals.
• Accurate frequency analysis using Fast Fourier Transform (FFT).
• Control of external devices via four I/O ports.
• PWM signal generation (3Hz to 10MHz).
• Testing integrated circuits (ICs) with various digital interfaces (SPI, I2C, UART, 1-WIRE).
• Power supply (+3.3V and +5V, up to 30mA).
• Data acquisition system (compatible with various sensors: temperature, humidity, irradiance, etc.).
• High-resistance state detection on I/O ports (Z-state).
