DC 5V 0.96" LCD Oscilloscope DIY Kit – STC MCU USB

Build Your Own Oscilloscope – DC 5V DIY Kit with 0.96" LCD Display

Take your electronics learning and prototyping to the next level with this DC 5V 0.96-inch DOS LCD Oscilloscope DIY Kit. Powered by an STC microcontroller and equipped with a micro USB interface, this hands-on kit is perfect for hobbyists, students, and makers who want a compact, functional oscilloscope they can assemble themselves. Made in Mainland China.

Key Features

• Three Trigger Modes: Auto, Normal, and Single — giving you full control over how signals are captured and displayed.
• Trigger Slope Selection: Choose whether the trigger fires on the rising or falling edge of a signal for precise waveform capture.
• Adjustable Trigger Level: Ensures a stable display for repetitive signals and reliable single-event capture.
• Onboard Waveform Generator: Built-in PWM (Pulse Width Modulation) and SIN (Sine Wave) generators; adjust RP1 and RP2 to vary amplitude.
• EEPROM Settings Save: All parameters from both the settings and main screens are automatically stored when you exit the menu — no need to reconfigure every session.
• Sampling Indicator LED: Lights up during active sampling so you always know when the device is measuring.
• Low Power Consumption: Runs efficiently on DC 5V via micro USB.
• Wide Voltage Range: Measures 0–30V (requires LSB adjustment), suitable for a broad range of electronic circuits.

Frequently Asked Questions

Q: What microcontroller does this oscilloscope DIY kit use?

A: This kit is built around an STC microcontroller in a TQFP package. The STC MCU handles all signal sampling, display output to the 0.96-inch DOS LCD, and control logic for the three trigger modes.

Q: What is the maximum voltage this oscilloscope kit can measure?

A: The oscilloscope kit supports a voltage measurement range of 0–30V. Note that accurate readings at higher voltages require LSB (least significant bit) adjustment as described in the product documentation.

Q: Does this kit require soldering to assemble?

A: Yes, this is a DIY electronics kit intended for hands-on assembly. Soldering skills are recommended. It is an excellent project for electronics students and hobbyists looking to build and understand oscilloscope circuits.

Q: How is the oscilloscope kit powered?

A: The kit is powered via a standard micro USB cable supplying DC 5V — the same connector used by many smartphones and Arduino boards, making it easy to power from a USB charger or computer port.

Q: Can this oscilloscope kit generate waveforms as well as measure them?

A: Yes! The kit includes a built-in waveform generator capable of producing PWM (Pulse Width Modulation) and SIN (Sine Wave) signals. The amplitude of each can be adjusted using the onboard potentiometers RP1 and RP2.
