Launch the executable file. Click the "Port" dropdown menu and select your device. Set the baud rate to match your microcontroller firmware (default is often 115200). Step 3: Open the Connection
. It is especially popular for testing embedded systems like Arduino, STM32, or ESP8266 because it allows for direct data exchange without a complex IDE. Key Features Portability
: Easily save incoming data streams directly to a .txt or .log file for later analysis, a must-have for catching intermittent communication errors.
Append precise millisecond timestamps to incoming or outgoing data packages to analyze latency and response intervals. Sscom V5.13.1 English Version
is a very popular, lightweight, and robust serial port debugging tool widely used by embedded engineers and hobbyists. While originally developed in China, the "English Version" usually refers to the version where the UI has been translated or the standard version where icons are self-explanatory.
Sscom buffers everything in memory. For long-term logging (hours), use the "Write to file directly" option (File → Save to file). This bypasses the display buffer.
While tools like PuTTY, Tera Term, or RealTerm exist, SSCOM V5.13.1 remains a preferred choice for hardware developers due to its specific optimization for embedded engineering. Unlike PuTTY, which is designed primarily as an SSH/Telnet terminal, SSCOM focuses purely on hardware interaction. Features like the dedicated HEX panel, real-time CRC generation, and multi-string macro buttons are natively built into its main window, saving developers from digging through complex nested menus. Conclusion Launch the executable file
To help me tailor any specific information you might need next, tell me:
Connect your hardware to your PC using a USB-to-TTL adapter.
Check and "HEXShow" if you are working with hexadecimal bytes. Step 3: Open the Connection
Configuring the software requires matching your parameters exactly to the connected hardware. Serial Port Settings
Leave them unchecked for standard text (ASCII) communication.
For the rest of us—hobbyists tinkering with ESP32s, professionals validating RS-485 networks, or students learning microcontroller protocols— remains a timeless, underappreciated workhorse.
The story of is one of a "no-nonsense" legacy tool that has remained a staple for hardware engineers and developers despite the emergence of newer software. It serves as a specialized serial communication port (UART) debugging tool, primarily used to send and receive data between a PC and embedded hardware like Arduino, STM32, or industrial modules.
