Key Features: 5 V power supplied by a USB connector USB 2.0 full-speed compatible interface (USB Type-A to Mini-B cable provided) Direct firmware update support (DFU) Status LED blinking during the communication with the PC The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontrollers. The single-wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board.STM8 applications use the USB full-speed interface to communicate with the ST Visual Develop (STVD-STM8) or ST Visual Programmer (STVP-STM8) software, or with integrated development environments from third-parties.STM32 applications use the USB full-speed interface to communicate with the STM32CubeIDE software tool or with integrated development environments from third-parties.Item SpecificsOperating temperature: 0 degC to 50 degCSWIM application voltage support: 1.65 V to 5.5 VSWIM low-speed and high-speed modes supportSWIM programming speed rates: 9.7 kbyte/s in low-speed, 12.8 kbyte/s in high-speedSWIM cable for connection to an application with an ERNI standard connectorVertical connector reference: 284697 or 214017Horizontal connector reference: 214012JTAG/SWD 5 V tolerant inputs application voltage support: 1.65 V to 3.6 VSWIM cable for connection to an application with pin headers or 2.54 mm pitch connectorJTAG cable for connection to a standard JTAG 20-pin 2.54 mm pitch connector
