** [[STM32 Black Pill]] - CPU card
 +
*** Preferred choice due to nearly unlimited resources
 +
** Previous CPU choices
 +
*** [[BLUE-PILL-HUB]]
 +
**** FTDI card required

 +
** Add the URL to Additional Board Manager URLs text box:
 +
*** https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json
 +
** Go to Tools > Board > Boards Manager
 +
** Search for STM32, select latest version and click Install.

 +
=== DFU Programming ===
 +
 
 +
[[file:STM32F4-Black-Pill-Board-oriented.jpg]]
 +
 
 +
** Start the STM32CubeProg
 +
** From the Tools > Board > STM32 Board, select Generic STM32F4 series
 +
** Select Tools > Board Part Number > BlackPill F411CE
 +
** Under USB Support, select CDC (generic "Serial" supersede U(S)ART)
 +
** Under Upload method, select SMT32CubeProgrammer(DFU)
 +
** Use the onboard BOOT0 and NRST button to put the board into bootloader mode:
 +
*** press and hold the BOOT0 button
 +
*** press and release NRST (reset) button to power cycle the processor
 +
**** alternate is to press the Reset button on the [[BLACK-PILL-HUB]] card
 +
*** release BOOT0 button
 +
*** Sometimes removing the USB cable and plugging it back in while pressing BOOT0 button works better
 +
** Upload sketch
