Frequently Asked Questions
Have a Question?
-
Can this adapter power multiple target boards simultaneously?
The adapter is designed for single target applications. For multiple targets, consider individual adapters or higher-current solutions like the 5V Target Supply Adapter.
-
What connector type does the adapter use?
The adapter uses standard 20-pin 0.1" (2.54mm) IDC connectors - socket for J-Link connection, header for target connection.
-
How does the power LED indicate adapter status?
The integrated LED illuminates when the adapter is providing power to the target, offering immediate visual confirmation of operational status.
-
Is any configuration software required for the adapter?
No software configuration is needed. The adapter operates immediately upon connection between your J-Link probe and target hardware.
-
Can I use this adapter with battery-powered J-Link probes?
Yes, though some battery-powered probes like Flasher Portable may require additional resistor adjustment (SMD 1206) for optimal operation.
-
What is the maximum current capability at lower voltages?
Current capability decreases with voltage: 1.8V provides 200mA maximum, 1.0V provides 150mA maximum. Exceeding these limits may damage the adapter.
-
Does the adapter affect debug signal quality or timing?
No, the adapter maintains 1:1 connectivity for all debug signals with transparent pass-through, ensuring no impact on JTAG, SWD, or SWO functionality.
-
Which J-Link debug probes are compatible with this adapter?
The adapter works with all SEGGER J-Link models including Pro, ULTRA+, PLUS, BASE variants, and Flasher programming tools.
-
How do I adjust the output voltage for different target requirements?
Voltage adjustment requires replacing a single SMD 0805 resistor on the adapter. The range extends from 0.8V to 3.6V with corresponding current limitations.
-
What voltage does the Target Supply Adapter provide by default?
The adapter provides 3.3V at up to 400mA by default, suitable for most ARM Cortex-M and similar microcontroller applications.
