Overview

J-Link Supply Adapter

The Supply Adapter provides a manually adjustable I/O voltage from 1.2 V to 5.0 V and eliminates the need for VTRef from the target board. It connects between a J-Link or Flasher and the target while maintaining the debug signal connections, reducing the number of connections required on the target.

1.2 V–5.0 V, adjustable
Default I/O voltage
3.3 V
Voltage adjustment
Single resistor, SMD 0603, soldering required
Connector
20-pin, 0.1" socket and header
Signal connection
1:1 connection, except VTRef / pin 1

Schematics

Schematic diagram showing connections between a probe/programmer and a target device, detailing various pins (VTREF, TRST, TDI, etc.). It includes a voltage regulator (VREG) connected to the MCP1826T DC component and resistance values (Rx) corresponding to different voltage references (VTREF).

Suitable products

Flasher

A handheld device labeled "Flasher" from SEGGER, primarily gray with blue rubber edges. It features three status indicators: "Ready" (OK), "Not ready," and "Fail," along with a "PROG" button. This device is used for programming and debugging electronics.
