Specifications

Microcontroller
  • 32bit STM32F303 Cortex M4 core with FPU

  • 72 MHz

  • 40 Kb RAM

  • 256 Kb Flash

Interfaces

The module can interface with infrared and ultrasonic proximity sensors providing analog or digital measurements. Analog measurements can vary from 0 to 3.3 V. Digital measurements are acquired by reading the duration of the high or low part of a PWM signal.
