 The hardware is only designed for signals speeds up to 20 MHz.
 The signals can be driven using 3.3 V push-pull mode, or 1.6 to 5.5 V open-drain mode with 2 kOhm embedded pull-up resistors (can be increased using external resistor).

 The BusVoodoo is pretty much unbrickable.

   - finally you can use the SWD pins on the programming connector to [[stm32f1xx#swj|flash using SWD]], provided you have and SWD adapter. This also allows to properly debug the firmware. :!: For some unknown reason sometimes after power-up the SWD adapter will not be able to find the micro-controller. Briefly reset the micro-controller by shorting RST to ground using tweezers (follow the RST indication on the board). From there on it will always be detected.
   - if none of the above methods work, the device is definitely bricked (or defective). congratulations.
