Compatible with J-Link OB ARM Debugger SWD Programmer STM32 Downloader Jlink Generation v8Compatible J-Link OB ARM Debug

Product Introduction J-Link- OB is a set of independent debug downloader developed by SEGGER, which is usually designed on the evaluation boards ("on-board") of major companies, which is why the suffix is ​​"OB". This set of download debugger named "J-Link-OB" has USB communication function and can communicate with PC, and the other end communicates with supported devices through SWD/JTAG to complete the debugging download and debugging task. Compared with the original J-Link OB, our J-Link OB debugger lacks the JTAG interface and only retains the SWD interface to debug and download the MCUs of many companies that use the ARM core. Supported objects are all ARM7\\9\\11, Cortex-M0\\M1\\M2\\M3\\M4\\A5\\A8\\A9 series embedded microcontrollers with SWD interface. Manufacturers that support MCU include ST (STMicroelectronics), Freecale (Freescale), nuvoton (New Tang), NXP (NXP), TI (Texas Instruments), Cypress ( Cypress), Atmel (Aitme Seoul), Analog (Adeno), Fujitsu (Fuji), Toshiba (Toshiba) Energy Micro, etc. Connection mode SWD mode supported IDE software J-Flash ARM, Keil MDK-ARM, IAR EWARM, CoIDE, mikroC PRO for ARM, nRFgo Studio function, performance programming function: can program FLASH ROM, EEPROM, AFR, etc. Function: Support various debugging methods such as full-speed operation, single-step debugging, breakpoint debugging, etc., and can view IO status, variable data, etc. Programming performance: USB2.0 interface is used for SWD download, and the download speed is fast! Performance: Use USB2.0 interface for debugging, single-step debugging, breakpoint debugging, fast response! The store independently designs and develops, provides technical support, and develops a sharp tool for learning ARM, use it with confidence! Product Image Product features of the front and back pictures 1. The interface is simplified, and the four-wire system is adopted: VCC, SWDIO, SWCLK, and GND. Compared with JTAG, it can save several IO ports and complete high-speed debugging and downloading. 2. It is fully compatible with traditional J-Link and has all the functions of J-Link. 3. Use the Mirco USB interface (the kind currently used by smartphones), and the data cable is universal. 4. The 3.3V output can also supply power to the target board, which is convenient for users to debug and program download. 5. On-board self-recovery fuse to avoid damage caused by short circuit and make the board safer. 6. It has a unique ID mark, and there is no conflict when debugging multiple devices at the same time. 7. Add a transparent heat shrink tube, which is more beautiful and more intimate protection. 8. Stable work, no missing firmware. 9. Only the size of a U disk, the circuit is simple, stable, reliable, and easy to move and carry.

The forum address is: http://www.vcc-gnd. com/ Comparison between J-Link OB and ST-Link V2: The difference between SWD and JTAG: Compared with the JTAG interface, the SWD interface needs at least 3 pins (SWDIO/SWCLK/GND) to complete the debugging and downloading task. It is recommended to use the SWD download mode, the interface comparison is as follows Instructions for use: The core board of Xiaodian's STM32 series has an onboard SWD debugging interface, and the line sequence of the SWD debugging interface of J-Link OB is consistent. Debugging is very convenient. The wiring is shown in the figure below: If the core board you use is a 20pin JTAG debugging interface, the wiring method is as shown in the figure below Instructions for use: We may not notice a problem when we program the target board, that is, when the USB port of the target board is powered by a USB cable, the VCC of our debugger is connected to the target board. In this way, there may be a phenomenon of burning the board (it may be debugging J-Link OB, or it may be the target board). In short, this will be very dangerous. The VCC connection of the J -Link OB is to supply power to the target board. With its power supply, the connection of the USB port does not need to be connected. When both ends are connected at the same time, it belongs to cross power supply. In short, choose one power supply method, and do not supply power at the same time. In order to reduce our unnecessary losses, Amoy friends please pay attention. . Shipping list : 1. J-Link OB debugger 1 piece 2. USB cable type A male port to Micro male port 1 piece 3.
