The SEGGER Target Supply Adapter (8.06.18) eliminates the need for separate power supplies during embedded system debugging by providing clean, regulated power directly from your J-Link debug probe. With its default 3.3V output at 400mA, this adapter suits the majority of modern microcontroller applications whilst offering flexibility for custom voltage requirements through simple resistor modification.
Engineered for reliability, the adapter features the MCP1826T LDO voltage regulator and maintains complete electrical isolation between power and debug signal paths. The integrated power LED provides immediate visual confirmation of output status, whilst the robust 20-pin connector system ensures reliable connections in demanding development environments.
Perfect for engineers developing battery-powered IoT devices, sensor networks, and embedded systems requiring precise power control during debugging and programming operations.
Compatible with all SEGGER J-Link debug probes and Flasher programming tools, this adapter integrates seamlessly into existing development workflows whilst providing the power supply flexibility essential for modern embedded development.

- 1577356: What voltage does the Target Supply Adapter provide by default?***SIMP***The adapter provides 3.3V at up to 400mA by default, suitable for most ARM Cortex-M and similar microcontroller applications.
- 1577357: How do I adjust the output voltage for different target requirements?***SIMP***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.
- 1577360: Which J-Link debug probes are compatible with this adapter?***SIMP***The adapter works with all SEGGER J-Link models including Pro, ULTRA+, PLUS, BASE variants, and Flasher programming tools.
- 1577361: Does the adapter affect debug signal quality or timing?***SIMP***No, the adapter maintains 1:1 connectivity for all debug signals with transparent pass-through, ensuring no impact on JTAG, SWD, or SWO functionality.
- 1577362: What is the maximum current capability at lower voltages?***SIMP***Current capability decreases with voltage: 1.8V provides 200mA maximum, 1.0V provides 150mA maximum. Exceeding these limits may damage the adapter.
- 1577363: Can I use this adapter with battery-powered J-Link probes?***SIMP***Yes, though some battery-powered probes like Flasher Portable may require additional resistor adjustment (SMD 1206) for optimal operation.
- 1577365: Is any configuration software required for the adapter?***SIMP***No software configuration is needed. The adapter operates immediately upon connection between your J-Link probe and target hardware.
- 1577366: How does the power LED indicate adapter status?***SIMP***The integrated LED illuminates when the adapter is providing power to the target, offering immediate visual confirmation of operational status.
- 1577367: What connector type does the adapter use?***SIMP***The adapter uses standard 20-pin 0.1" (2.54mm) IDC connectors - socket for J-Link connection, header for target connection.
- 1577369: Can this adapter power multiple target boards simultaneously?***SIMP***The adapter is designed for single target applications. For multiple targets, consider individual adapters or higher-current solutions like the
