I am practiced in doing fine soldering work, but soldering the selected SMD components was nevertheless challenging. In the end, however, the soldering work was successful. The PicoGlitcher is working as expected and I am able to glitch targets. For a test if everything works, I ran a glitch against an STM32F4 microcontroller. Although RDP level 1 was activated, the target responds with an "ACK" after a few attempts when accessing the flash memory in bootloader mode.

The PicoGlitcher v1 actually works!
