Demanding graphic interfaces, smart actuator control and monitoring is all achievable through the utilization of the STM32H7 dual core family. This device performs complex actuator control: heater, DC motor, pump in order to process the milk per given specification…. and if you have good soldering eye you might have caught that there is a small raisin ball between pins 18 & 19 ;).

Requirements:

• WIFI/BLE interface for device configuration and firmware update,
• 2x DC motor, fan and pump control,
• AC/DC converter and AC load control,
• User interaction through the LCD interface.
