The STM32F423 Lite module is based on the STM32F423CHU6 (100MHz, 1500KB Flash, 320KB RAM) microcontrollers with the Cortex M4 architecture (extended with FPU).


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 STM32F423 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
  • PLC
  • Inverters
  • Circuit breakers
  • Medical devices
  • Electric drives
