Feature Highlights: 1. Simple 4-Line SWD Interface – Uses just four connections: VCC, SWDIO, SWCLK, and GND for fast, high-speed downloading and simulation. 2. Full Compatibility with V8 Simulator – Works exactly like the traditional V8 debugger, with all the same functions. 3. Universal Micro-USB Port – Easy to connect using a common Android phone cable. 4. 3.3V Power Output – Supplies up to 300mA to power your target board during debugging. 5. Built-in Safety Protection – Features a self-recovery fuse and ESD protection for safe, stable operation. 6. Reliable & Upgradable Firmware – Stable performance with automatic updates—no risk of firmware damage. 7. Compact & Portable – U-disk sized design, easy to carry for work or travel. Product Details: This 2-in-1 debugger combines programming and simulation in one handy tool. It supports burning FLASH ROM, EEPROM, AFR, and more. For debugging, it enables full-speed running, single-step, breakpoint debugging, and real-time monitoring of IO status and variables. With USB2.0 and SWD interfaces, both downloading and simulation are fast and responsive. Perfect for STM32 and other ARM-based development.
