STM32F4xx Lite - a tiny microBUS Cortex M4 SoM

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

·         STM32F401CEU6 (84Mhz, 256KB Flash, 96KB RAM)

·         STM32F411CEU6 (100Mhz, 512KB Flash, 128KB RAM)

·         STM32F423CHU6 (100Mhz, 1500KB Flash, 320KB RAM)

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

Debugging interface - SWD. External connectors - I²C, USB, mikroBUS^TM and two auxiliary 4-pin connectors.

Input Power – 5V. The voltage regulator is Microchip's MIC5528, which provides 500 mA output current. The module has a RESET button and three LEDs (power and two program-controlled).

STM32F4xx Lite makes it easy to implement IoT projects (smart sensors, climate control, industrial automation) using expansion modules with mikroBUS^TM interface, Qwiic^® and Grove Systems peripherals (sensors and devices), as well as any other I²C bus-controlled modules. You no longer need to mockup the system, and then think first about how to make a prototype, and then how to start serial production. You can assemble the desired configuration and after debugging you only need to put the system into the case and buy the selected boards to start production.

The size of the 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
• PLC
• Inverters
• Circuit breakers
• Medical devices
• Electric drives
• Sensor hubs
• Security systems
