One person is also specifically working on a MicroPython port for WeAct v1.3 board.īlack Pill / WeAct v1.3 board can be purchased on Aliexpress for $2.79 (STM32F401CCU6 ) or $3.96 (STM32F411CEU6). I can not see Arduino support yet for the board, but an STM32F401CC board called BlackBill F401CC is supported in Arduino Core for STM32 repository, and I believe it may be this exact board (TBC). “Blue Pill” is just a nickname for this type of board, and we can see the PCB is named WeAct V1.3. 1.We’ll create a sample Blue Pill program with Visual Studio Code and PlatformIO 2.Study the Linker Script that was used to create the Blue Pill executable, and the Memory Layout that it enforces 3.Learn what’s inside the Text, Data and BSS Sections of a Blue Pill executable 4. The new boards get a faster microcontroller with an FPU and much more memory and storage to play with, and you could even solder your own SPI flash. Power – 5V via USB, 2.0-3.6V power via 3.3V pin on SWD header.Black Pill STM32F411 only – Power button.Expansion – 2x 20-pin with power signals, I2C, SPI, GPIOs, ADC inputs, etc….Debugging – 4x pin SWD header or USB port.Black Pill – 1x USB Type-C port for power and programming.Blue Pill – 1x micro USB port for power and programming.STMicro STM32F411CEU6 Arm Cortex-M4F MCU 100 MHz with 512KB flash, 128KB SRAM.STMicro STM32F401CCU6 Arm Cortex-M4F MCU 84 MHz with 256 KB flash, 64KB SRAM.STMicro STM32F103C8T6 ARM Cortex-M3 MCU 72 MHz with 64KB flash memory, 20KB SRAM.Specifications for the Blue Pill & Black Pill boards (new features in bold): It’s black, so instead, I’ll call Black Bill as some others appear to do. I’ve just been informed the board got an upgrade of sorts with a “Blue Pill 2” board featuring either STM32F401CCU6 or STM32F411CEU6 Arm Cortex-M4F microcontroller, and a USB Type-C port for power and programming. STM32 “Blue Pill” is a popular, and cheap (>$2) development board based on STMicro STM32F103C8T6 Arm Cortex-M3 microcontroller and programmable with the Arduino IDE.
