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.

Frequently Asked Questions
Have a Question?
-
What's included in the software package?
The complete professional suite includes unlimited flash breakpoints, J-Flash programming software, Ozone graphical debugger, RDI/RDDI interfaces, GDB Server, and one year of email support with free software updates.
-
Is the wireless connection secure for commercial development?
The J-Link WiFi supports standard WiFi security protocols including WPA2. For sensitive projects, it can operate on isolated networks or VPNs to maintain security while enabling wireless debugging.
-
Can I power my target device through the J-Link WiFi?
Yes, pin 19 provides 5V at up to 300mA to power small target boards. Larger systems will need separate power supplies, but the probe can still monitor target voltage levels for debugging.
-
Does the J-Link WiFi work with all major development environments?
Yes, it's compatible with Eclipse, Keil MDK, IAR EWARM, SEGGER Embedded Studio, GDB-based IDEs, and many others. The probe appears as a standard J-Link to your development tools.
-
What's the maximum distance for WiFi debugging?
Range depends on your WiFi infrastructure. With standard routers, expect 30-50 metres indoors. Using enterprise WiFi systems or repeaters can extend this significantly for large facilities or outdoor applications.
-
Can multiple engineers debug the same device remotely?
Yes, using J-Link Remote Server, multiple developers can access the same target device over the network. This enables collaborative debugging sessions and remote development workflows.
-
How do I configure the WiFi network settings?
Connect via USB initially, then access the built-in web server through your browser. The web interface allows you to configure WiFi networks, set static IP addresses, and manage connection settings without external software.
-
Can the J-Link WiFi debug devices while they're moving or rotating?
Yes, the wireless interface eliminates cable constraints, making it perfect for debugging robotic systems, rotating machinery, or any mobile embedded application. The WiFi connection maintains stable communication during movement.
-
Which microcontrollers are supported by the J-Link WiFi?
The probe supports ARM Cortex-A/R/M cores, RISC-V processors, plus legacy ARM7/9/11, Microchip PIC32, Renesas RX, and SiLabs 8051 devices. It's compatible with thousands of devices from major semiconductor manufacturers.
-
What makes the J-Link WiFi different from other wireless debug probes?
The J-Link WiFi offers professional-grade debugging at 15MHz over WiFi with a built-in web server for configuration. Unlike hobbyist solutions, it includes comprehensive software licenses, unlimited flash breakpoints, and enterprise-level reliability for production environments.
