DescriptionThe 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 boardThe ST-Link comes with a cable that has four female headers on each end that will connect to four pins on the back of the ST-Link. The pins we’re going to be using as the SWCLK, SWDIO, the SWCLK is the clock and the SWDIO is the data, input/output. We’ll be using the ground (GND) and the 3.3v. Package includes: 1× ST-LINK V2 Simulator Download Programmer 1x JTAG/serial wire debugging (SWD)
