Debugger Hardware
Black Magic Probe firmware can be compiled for many different target platforms. Here is a short list with descriptions of different targets.
The following is a list of official hardware supported by the Native target that is the default compilation target of Black Magic Probe firmware.

Status Legacy (not in production)
The original first hardware. Offers a legacy ARM JTAG 0.1" 20Pin connector. Some of the pins of the 20Pin connector carry TX and RX of a serial interface. This makes the connector not 100% compatible to a default 20Pin JTAG connector.
The board has a MOSFET to switch 3.3V power supply to the target.
All IO is buffered through a TXS0108 Texas Instruments bidirectional level shifter.

Status Active
Small version of the Black Magic Probe also known as BMPM1. The form factor was inspired by the Floss JTAG FTDI based adapter. The board offers an ARM Cortex 0.05" 10Pin connector on the top of the board and a Molex Picoblade 4Pin UART serial connector on the back of the board.
The board has a MOSFET to switch 3.3V power supply to the target the same way Black Magic Probe did.
This board does not buffer the JTAG or serial pins in any way, they are connected directly to the STM32.

Status In development
Same form factor as the predecessor BMPM1. Following is a list of main differences to the predecessor.
- Adds TXS0108 level shifter for wider range of targets. This will add support for low voltage targets that run on 1.8V.
- Uses two MOSFET to prevent powering the BMPM in reverse through the MOSFET body diodes.
- Uses USB Micro connector as it is by now more wide spread than USB Mini.
It is possible to run the Black Magic Probe firmware on your PC and have it bit bang using a USB attached FTDI adapter. This is very slow but can be used for debugging and testing purposes of the Black Magic firmware.
You can compile the firmware for an ST Link debugger. These are often included on ST Discovery evaluation boards. You can replace the ST Link firmware on your discovery board with Black Magic Probe firmware. Usually this leads to more stable operation and easier use than the ST tools. There is are several tutorials for how to do it even if you don't have a JTAG adapter yet and no way to bootstrap. :)
You can run the Black Magic Probe firmware on the "target" processor of an ST F4 discovery board. This among others useful if you want to bootstrap your F4 Discovery board ST Link programmer without having any other means of programming it.
This target is the programmer integrated on the STM8S Discovery board.
This target is the programmer integrated on the TI Launchpad board.
