Professional Wireless Debugging for Mobile Applications
The J-Link WiFi represents a breakthrough in embedded debugging technology, combining SEGGER's industry-leading debug capabilities with wireless connectivity. This JTAG/SWD debug probe operates at speeds up to 15MHz, delivering professional-grade debugging performance through a stable WiFi interface.
Wireless Freedom for Modern Development
Eliminate the constraints of physical connections when debugging mobile applications, robotic systems, or embedded devices that require movement during testing. The J-Link WiFi enables remote debugging scenarios previously impossible with traditional wired probes.
Wiring Quick-Start
Connect your target system using the standard 20-pin JTAG/SWD interface:
| Pin | Signal | Description |
|---|---|---|
| 1 | VTref | Target reference voltage (1.2V - 5V) |
| 7 | SWDIO | Serial Wire Data I/O (bidirectional) |
| 9 | SWCLK | Serial Wire Clock |
| 13 | SWO | Serial Wire Output (trace data) |
| 15 | nRESET | Target reset (active low) |
| 19 | 5V Supply | Target power (max 300mA) |
Even-numbered pins (2, 4, 6, 8, 10, 12, 14, 16, 18, 20) connect to ground.
Network Configuration
The J-Link WiFi includes a built-in web server for easy network configuration. Connect via USB initially to configure WiFi settings through the web interface at the device's IP address.
