Schematic - Jlink V9

A common mistake in DIY debug probes (like the Bus Pirate or basic ST-Link clones) is connecting the MCU GPIO directly to the target device. This works, but it’s dangerous. If you connect a 3.3V probe to a 1.8V target (or worse, a voltage mismatch), you can fry the debug header or the target MCU.

The J-Link V9 schematic employs a sophisticated Voltage Translation & Buffering stage.

Before examining the schematic, one must understand the functional blocks. The J-Link V9 is not a single-chip solution; it is a composite device.
