The BOKRA STM32F4xx Lite module is based on the following microcontrollers with the Cortex M4 architecture (extended with FPU):


  • STM32F401CBU6 (84MHz, 256KB+64KB)
  • STM32F411CEU6 (100MHz, 512KB+128KB)
  • STM32F423CHU6 (100MHz, 1500KB+320KB)


The module can accommodate additional 4Mx8 or 16Mx8 flash memory.

Debug Interface - SWD.

Serial interfaces - SPI, I2C, USART, CAN, LIN

External connectors - USB, I2C and mikroBUS.


Input power supply - 5V. The voltage regulator is Microchip's MIC5528, providing 500 mA output current. The module has a RESET button and three LEDs (power and two software-controlled).


The size of the BOKRA STM32F4xx Lite module is 28.6 x 25.4 mm.


The site STMicroelectronics - manufacturer of the microcontroller - indicated that it is designed for a wide range of applications, such as:

  • Industrial Applications
