STM32 blue pill case (blackmagic programmer)

thingiverse

The high value blackmagic board can be transformed into a low cost bluepill probe, which supports SWD/JTAG debugging of numerous targets. To achieve this DFU/blackmagic.bin is necessary, can be programmed onto the stm32 using serial bootloader or with an STLINK. I've added the zip as compiling it can be a bit of work, target=STLINK. Pins are as follows: Pinout (SWD, 6 pin): - 1 - IO - B14 - 2 - Rst - A5 - 3 - Clk - B0 - 4 - n/c - 5 - Gnd - 6 - 3.3V Pinout (JTAG): - TDI - B14 - TDO - A7 - TCK - A6 - TMS - B0 Pinout (serial), provided by jonnyw2k: - Target(TXD) -> A3 (RXD on Bluepill/BMP) - Target(RXD) -> A2 (TXD on Bluepill/BMP) stlink platform github: https://github.com/blacksphere/blackmagic/blob/master/src/platforms/stlink/platform.h Dimensions I used are specific to my board, so I'm not sure how well other boards will fit. Pin header retention printed well enough, but glue would help. I managed to recover a SAMD21 using the debugger, still trying to figure out how to prevent it from being damaged. But otherwise it worked well to load .hex bootloader and code.
