● Using the Type-C interface is more stable, smaller and more convenient to use. ● The hardware adopts 500mA patch fuse, which can effectively prevent reverse connection and short circuit during debugging, 3.3V and 5V voltage output. ● It can replace ST-Link and J-Link for program download and debugging. ● Support all Cortex-M0/M3/M4/A7 core microcontrollers with SWD interface. ● USB-HID driver-free (WIN10), with a virtual serial port (CDC).
