 +The BusVoodoo implements numerous low-speed protocols.
 +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 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).

 But BusVoodoo will never replace dedicated tools (USB to UART dongle, JTAG adapter, flash programmer, ...) or prevent from using a development board to control all nifty protocol details. But BusVoodoo will never replace dedicated tools (USB to UART dongle, JTAG adapter, flash programmer, ...) or prevent from using a development board to control all nifty protocol details.
