M328 Arduino Based multi function Transistor Tester

Description

M328 Multi-functional Transistor Tester & Component Analyzer

Quickly identify and test a wide range of electronic components with this versatile M328-based tester. Ideal for hobbyists, students, and technicians, it automatically detects NPN/PNP transistors, MOSFETs (N/P channel), JFETs, diodes (including double diodes), thyristors/SCRs, triacs, resistors, capacitors, and inductors. Simply insert the component into the ZIF socket and press the button!

Beyond basic identification, this tester measures key parameters and functions as a basic signal generator and frequency meter.

Key Features:

• Automatic Component Detection: Identifies common semiconductor devices, resistors, capacitors, and inductors.

• Parameter Measurement:

  • Measures hFE (current gain) and Vbe (base-emitter voltage) for bipolar transistors.

  • Measures Vgs(th) (gate threshold voltage) and Cg (gate capacitance) for MOSFETs.

  • Measures resistance (including potentiometers) and inductance.

  • Measures capacitance and often ESR (Equivalent Series Resistance) for capacitors.

  • Displays diode forward voltage (Vf).

  • Shows component pinouts on the display.

• Additional Functions:

  • Square Wave Generator: Outputs various frequencies from 1Hz to 2MHz.

  • PWM Signal Generator: Generates PWM signals with adjustable duty cycle (1-99%).

  • Frequency Meter: Measures external signal frequencies (check specific model documentation for range/limitations).

• Easy to Use:

  • Clear 16×2 Digital LCD display for readings and pinouts.

  • Simple one-button operation.

  • Zero Insertion Force (ZIF) socket for easy component connection.

  • Fast detection time (typically ~2 seconds, longer for large capacitors).

• Portable: Powered by a standard 9V battery (not included).

Ideal for:

• Quickly sorting and verifying components.

• Basic troubleshooting and repair.

• Educational purposes and learning about component characteristics.

Please Note: Battery (9V) is required and not included. Accuracy is suitable for hobbyist use but may not meet professional calibration standards.
