Seeed Studio XIAO Debug Mate is an open-source ESP32-S3 multi-tool that simplifies embedded system debugging with visual feedback. This all-in-one device features a standalone 2.01 inch TFT LCD display, LED status matrix, and native Seeed Studio XIAO support, delivering essential debugging functions: DAPLink chip-level debugging, built-in serial monitoring with UART passthrough, and accurate power consumption measurement. Plug-and-play design eliminates complex wiring for streamlined development.
3-in-1 Professional Development Tool
- DAPLink-Compatible SWD Interface for Professional Chip-Level Debugging: Powered by ESP32-S3 with full OpenOCD/PyOCD support, delivering professional-grade debugging capabilities. Set breakpoints, step through code, inspect memory, and access low-level hardware operations with precision. The integrated DAPLink firmware enables seamless SWD communication between your PC and target XIAO microcontroller, bringing lab-quality debugging tools to your desktop.
- Intelligent Serial Monitor & UART Passthrough: Monitor communications between your XIAO and the XIAO Debug Mate, or between the XIAO Debug Mate and external UART devices (Arduino, Raspberry Pi, Grove sensors). View real-time serial data on the onboard display for instant feedback, or redirect signals to your PC for detailed analysis. This intelligent switching eliminates multiple tools by providing complete visibility into all serial communications through a single, streamlined interface.
- Precision Power Profiling: Track power consumption down to μA levels with three specialized measurement interfaces. Monitor voltage/current readings, ultra-low-power states, and consumption patterns with peak/valley identification. Each unit is factory-calibrated for maximum accuracy (±10% accuracy @ 1-10μA), enabling confident battery life validation and energy optimization for both standalone XIAO boards and complete XIAO-based projects—ready to use out of the box.
Standalone Visual Feedback System
Monitor key system metrics without connecting to a PC. The integrated 2.01" LCD screen displays real-time serial communications, power consumption readings, and UART data streams, while the programmable LED matrix provides instant Baud rate indicators. Perfect for on-site field testing, mobile development, and quick system power consumption checks. (Special thanks to 啊猫啊狗晒太阳 (Ah Mao Ah Gou Shai Tai Yang) for the design inspiration for the LED matrix.）
Open-Source Platform Designed for XIAO with Universal Compatibility
Purpose-built for the Seeed Studio XIAO ecosystem with direct plug-and-play connection support—any pre-soldered XIAO board connects instantly without tedious wiring. The thoughtfully designed pin headers and sockets transform the device into a specialized expansion breadboard for XIAO development, providing abundant expansion options backed by robust power management and UART monitoring. While optimized for XIAO, the open-source design extends compatibility to any ARM Cortex-M microcontroller target via standard SWD and UART interfaces. Complete with a crisp 2.01" TFT display (240×296px) and 36-LED matrix, this versatile platform serves as both a professional debugging tool and a creative foundation for embedded projects.
