Overview
The DSO152 is an ultra-compact digital oscilloscope designed for the “budget-conscious” maker. Despite its small size, it features a crisp 2.8-inch colour TFT display and a refresh rate optimized for low-frequency signals. It is the perfect tool for debugging $555$ timer circuits, checking PWM signals from an Arduino, or troubleshooting basic power supply ripples.
Key Features
One-Key AUTO: No complex setup required. Press one button and the DSO152 automatically scales the voltage and time base to display your waveform.
Highly Portable: Smaller than a smartphone and weighs almost nothing—ideal for students carrying gear between home and university labs.
Built-in Calibration: Includes a $1\text{kHz}$ square wave output for probe calibration and testing.
Firmware Upgradable: Supports PC firmware updates via USB to ensure you always have the latest features and stability.
High-Voltage Protection: Even at this price point, it includes protection up to $400\text{V}$ (with a 10X probe), making it safer for beginners.

Why Choose the DSO152?
The “First Scope”: If you’ve never used an oscilloscope before, this is the least intimidating and most affordable way to learn.
Arduino Debugging: Most Arduino projects (LED dimming, motor control, IR remotes) operate well within the $200\text{kHz}$ range.
Pocket Logic: It fits in your pocket, making it the ultimate tool for quick “on-site” checks of battery voltages or low-speed signals.
