DORHEA Oscilloscope Kit Cortex-M3 STM32F103C8 with 2.4 inch TFT

Description

Product Overview

The DORHEA Oscilloscope Kit is engineered as a compact, yet fully featured digital oscilloscope for educational, hobbyist, and light‑industrial applications. At its heart lies a high‑performance ARM Cortex‑M3 microcontroller (STM32F103C8) that drives a 2.4‑inch color TFT display, providing vivid, 320×240 pixel graphics for clear waveform representation. The kit includes a HOLD function that freezes the displayed waveform at any moment, allowing detailed inspection of transient events. Users can select from automatic, regular, and one‑shot acquisition modes, and trigger on either rising or falling edges, with the ability to view a previous trigger waveform (negative delay) for context.

All critical oscilloscope circuitry is pre‑soldered onto the board, eliminating the need for manual soldering of surface‑mount components. The case arrives unassembled, encouraging hands‑on learning and customization. Adjustable vertical displacement lets users fine‑tune the signal baseline, while the included instruction manual guides assembly and basic operation. The device stores captured waveforms in non‑volatile memory, ensuring data is retained even after power loss. Additional digital readouts display key parameters such as frequency, period, pulse width, duty cycle, and statistical values (max, min, average, peak‑to‑peak). The kit’s open‑source firmware can be extended, offering a platform for further development and experimentation.

Usage

This oscilloscope is ideal for a wide range of scenarios. In academic labs, it serves as a hands‑on teaching tool for electronics courses, allowing students to visualize signals from sensors, microcontrollers, and simple circuits. Hobbyists building Arduino or Raspberry Pi projects can quickly diagnose timing issues, verify PWM outputs, and monitor power supplies. Small‑scale engineers and technicians in prototype workshops benefit from its portability and low cost when troubleshooting analog circuits, motor drivers, or communication lines.

The kit operates comfortably within a 3.3 V supply range, making it compatible with most development boards. Its 1 Hz to 3.3 V square‑wave generator provides a built‑in test signal, while external probes can be attached to measure real‑world waveforms up to 20 MHz bandwidth. The intuitive menu system, navigated via a few tactile buttons, reduces the learning curve, and the waveform storage feature ensures that critical data can be reviewed later or exported for further analysis.
