Explore new microcontroller worlds with an ST-Link Programmer & Emulator / Debugging dongle. This little USB stick contains a microcontroller with the code for ST's classic programmer/emulator for STM8 and STM32 bit processors. Since STM's are so common, this tool will come in handy whenever you encounter them. You can even get 5V and regulated 3.3V power!
Comes with one USB stick and a couple pieces of female-female jumpers. You may want to peruse our jumper selection if you need more or different sizes.
We wired it up to an STM32 and ran ST-Link, and worked great! You can even update the firmware on the dongle as necessary, it has a DFU bootloader (we unplugged/replugged it from USB to kick off the DFU process)
For tons more details and for drivers and software, check out ST's page on the ST-Link
Note: These ST-Links come in a variety of different colors. We're unable to control the color you receive.
TECHNICAL DETAILS
- USB stick dimensions: 54mm x 20mm x 9mm / 2.1" x 0.8" x 0.35"
- Wires Length: 200mm / 7.9"
