DOMini: A Versatile Digital Oscilloscope for Diverse Applications

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

Key Features:

• Six measurement channels (four analog + two digital).
• Four measurement modes: single, normal (standby), auto, and recorder.
• Trigger events synchronized with data acquisition.
• Real-time Fourier analysis for frequency domain insights.
• Extensive waveform memory: 13,200 measurements (up to 26,400 for the logic analyzer).
• High-speed sampling: Analog channels from 5,000 to 1,000,000 samples per second; digital channels from 5,000 to 12,000,000 samples per second.
• Dual voltage supply: +3.3V and +5V.
• Probe calibration and unit customization.
• Compatibility with standard x1 and x10 oscilloscope probes.
• Wide voltage measurement range: ±5V, 0-10V (±15V, 0-30V with x1 probe).
• 10-bit resolution ADC for precise measurements.
• Four digital PWM input/output ports.
• Comprehensive digital interfaces: SPI, I2C, UART, and 1-WIRE.

Applications:

• Comprehensive analysis of analog and digital signals.
• Precise frequency signal analysis using Fast Fourier Transform (FFT).
• External device control via four I/O ports.
• PWM signal generation (3Hz to 10MHz).
• Testing integrated circuits with digital interfaces (SPI, I2C, UART, 1-WIRE).
• Power supply (+3.3V and +5V, up to 30mA).
• Data acquisition system (compatible with various sensors like temperature, humidity, and irradiance sensors).
• High-impedance input/output port state detection (Z-state).

The DOMini provides a robust and versatile solution for a broad spectrum of electronic testing and analysis needs.
