Programming Voltage Adapter

The Programming Voltage Adapter can directly be inserted between a J-Link and the debug cable and provides voltages to the target for programming targets with voltage requirements beyond 5 V.

SEGGER Debug & Trace Probes

Overview

The Programming Voltage Adapter can be used to provide two dedicated voltages to a target: a programming voltage, and a target supply voltage. Both voltages are provided by an external power supply to a connector on the adapter and are controlled by one of SEGGER's J-Link debug probes. This adapter is especially useful for programming targets that do not feature low-voltage programming or for targets with a voltage requirement other than 5 V.

If the target needs a 5 V supply, a jumper on the adapter can be switched to use the 5 V from the J-Link debug probe so only one external power supply is required (providing the programming voltage). Both channels accept a voltage in the range 4-20 V and can handle a maximum current of 500 mA.

The Programming Voltage Adapter has a standard 20-pin 0.1" socket towards the J-Link and a standard 20-pin 0.1" header on the target side. It can directly be inserted between the J-Link and the debug cable maintaining a 1:1 connection of all debug signals except pin 17 which carries the programming voltage.
