J-Link-OB is a set of independent simulation debugger developed by SEGGER, which is usually designed on the evaluation board of the major companies ("on-board"), which is also the reason for the suffix "OB". The simulator called "J-Link- OB" has a USB communication function that communicates with the PC and the other end communicates with the supportable device via SWD / JTAG to complete the debug download debug task.
Our J-Link OB simulation debugger compared to the original J-Link OB less JTAG interface, leaving only the SWD interface to the use of many ARM MCU kernel debugging debugging.

Features
1, simplified interface, using four-wire: VCC, SWDIO, SWCLK, GND four interfaces, compared with JTAG, can save a number of IO port, complete high-speed debugging, download.
2, fully compatible with the traditional J-Link, with J-Link all the features.
3, the use of Mirco USB interface (currently the kind of smart phones), the data line common.
4,3.3V output, but also to the target board power supply, user-friendly debugging and download procedures.
5, onboard self-recovery fuse, to avoid short-circuit damage, so that the board more secure.
6, with a unique ID logo, multi-device debugging at the same time does not conflict.
7, the installation of transparent heat shrink tube, beautiful more intimate protection.
8, work is stable, no firmware loss phenomenon.
9, only U disk size, the circuit is simple, stable, reliable, easy to move and carry.
