Best Oscilloscope for Arduino and ESP32 Development in 2025
Microcontroller development with Arduino, ESP32, STM32, and similar platforms often requires more than a multimeter. An oscilloscope allows developers to visualize waveforms, debug communication protocols, analyze PWM signals, troubleshoot power issues, and inspect sensor outputs in real time.
The HANMATEK DOS1104 is a powerful yet affordable oscilloscope designed for embedded systems development. Featuring 4 channels, 110MHz bandwidth, and a 1GS/s real-time sampling rate, it provides the performance needed for analyzing UART, SPI, I²C, PWM, and other common microcontroller signals.
Its four-channel architecture enables simultaneous monitoring of multiple signals, making debugging faster and more efficient. Whether you're a student, maker, engineer, or repair technician, the DOS1104 offers excellent value and flexibility for modern electronics projects.
