Short Product Description

Upgrade your interface with crisp visuals.
This 12864 Graphic LCD Module delivers a sharp 128x64 pixel resolution on a stunning blue backlight with white pixels. Built with the versatile ST7920 controller, it supports both Parallel and SPI Serial modes, allowing you to save precious I/O pins on your Arduino or microcontroller. Perfect for displaying complex graphics, charts, and custom text.

Key Features

  • High-Res Graphic Display: 128x64 dot matrix resolution enables text, images, and graph rendering.
  • Crisp Visibility: Deep blue background with bright white pixels provides excellent contrast and aesthetics.
  • Dual Interface Modes: Supports both 6800 8-bit Parallel and Serial (SPI) modes (Selectable via Pin 15 PSB).
  • Standard 5V Logic: Seamlessly compatible with Arduino UNO, Mega, and other 5V logic controllers.
  • Adjustable Contrast: Dedicated V0 pin allows for precise brightness and contrast tuning via potentiometer.
  • Robust Mounting: Four corner mounting holes (3mm) for secure installation in enclosures.

Full Product Description

Transform the Way You Test Electronics

Are you tired of juggling bulky multimeter probes while trying to test microscopic SMD components? The FNIRSI LCR-ST2 is engineered to solve the frustration of modern electronics repair. It isn't just a tool; it's your pocket-sized diagnostic lab.

 

Precision Meets Versatility

Most portable testers fail at high frequencies. The LCR-ST2 breaks the mold with a professional 100Hz–100kHz frequency range and varying signal levels (up to 1.0V RMS). This ensures accurate "In-Circuit" testing for capacitors, inductors, and resistors, allowing you to measure ESR (Equivalent Series Resistance) with confidence—crucial for identifying bad capacitors in power supplies and motherboards.

 

Designed for the Workbench and the Field

What sets the ST2 apart is its unique 2-in-1 Modular Design. Use the precision gold-plated tweezer tips for tiny 0402/0603 SMDs, or instantly swap to the Kelvin Test Clips (included) for through-hole components and larger capacitors.

 

Work Smarter, Not Harder

  • Intelligent Sorting: Set your tolerance (e.g., 1% or 5%) and quickly sort through a pile of mixed components. The device automatically buzzes to tell you if a part is a "Pass" or "Fail."
  • Auto-Rotate Screen: Whether you are left-handed or right-handed, the 1.47" HD Color OLED display flips automatically to match your grip.
  • Secondary Parameters: Don't just see the capacitance; see the Dissipation Factor (D), Quality Factor (Q), and Phase Angle ($\theta$) simultaneously.

 

Package included:

  • LCR-ST2 Tweezer
  • Storage Bag
  • Curved Tip
  • Shorting Plate
  • Kelvin Test Clip

FAQ Section

Q: Can this measure ESR (Equivalent Series Resistance) for capacitors?

A: Yes! The LCR-ST2 measures ESR accurately. It also provides secondary parameters like Q (Quality Factor) and D (Dissipation Factor), making it perfect for checking the health of electrolytic capacitors in repair work.

Q: Can I use this on a powered circuit board?

A: While the device handles up to $\pm 30V$ in Voltage Mode, for LCR measurements (Resistance/Capacitance/Inductance), you must discharge capacitors and cut power to the board before testing to prevent damage to the meter.

Q: Is the battery replaceable?

A: The device uses a built-in 300mAh rechargeable lithium battery that charges via USB-C. It provides about 3 hours of continuous testing time, which is typically enough for several days of standard use.
