WIN10 driver free, but may need install in WIN7/8 Capable to program all ARM Cortex M core chips. Design and supported by ARM, (St-link for STM32, designed by ST company) Support our NRF51822 boards, tested with our nrf51822 board in arduino IDE Work well in MDK IDE, but NOT supported in IAR, please notice. Recognized as (CMSIS-DAP debugger) Support debugging in MDK IDE Fast speed, slightly slower than Jlink V8 Include extra driver, can also use as a normal USB-TTL tool. R2 Board Updates: Lead out all pins for use, when firmware flashed, can be used as a programmer, if not it can be used as a development board. Also can be used as USB-TTL serial tool. Programmer PORT SWD: front: SW_DIO, SW_CLK, SWO, TDI, RST (reset) back: VREF, U1TXD, U1RXD, GND, 3V3 For STM32 programming, need connect SW_DIO, SW_CLK, RST, 3V3 power and GND. Two status LED PB12, PB13 Use guide and documents see here.
