Black Pill Module

Not pin compatible with Blue Pill due to power pin locations

Reserved Pins

PA0 - On-board USER KEY - needs INPUT_PULLUP
PC13 - On-board LED
PB2 - BOOT1
- Pulling this pin down by external hardware causes the board to boot to serial
- Can be ignored by holding both reset and BOOT1 buttons on the Black Pill card
- Release reset button first
PA11 - USB-M
PA12 - USB-P
PA9 - Serial TX1
PA10 - Serial RX1

Second Serial Port - HardwareSerial

From HardwareSerial. The STM32 MCU's have several U(S)ART peripherals. By convenience, the U(S)ARTx number is used to define the Serialxinstance:

Serial1 for USART1
Serial2 for USART2
Serial3 for USART3
Serial4 for UART4
- For LPUART1 this is SerialLP1
By default, only one Serialx instance is available mapped to the generic Serial name.

To use a second serial port, a HardwareSerial object should be declared in the sketch before the setup() function:

//                      RX    TX
HardwareSerial Serial1(PA10, PA9);

void setup() {
  Serial1.begin(115200); 
}

void loop() {
  Serial1.println("Hello World!");
  delay(1000);
}

Connectors

Steps from Programming|Program STM32 Black Pill (STM32F401 / F411) with Arduino IDE (Windows OS)
- 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.
- Download and install STM32CubeProg from ST.com: [1]
- 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 STM32CubeProgrammer(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
  - release BOOT0 button
  - Sometimes removing the USB cable and plugging it back in while pressing BOOT0 button works better
- Upload sketch
