STMicroelectronics Enhances STM32G4 MCUs for New Discovery Kits and Firmware

September 11, 2019 Laura Dolan

STMicroelectronics has supplemented its STM32G4 microcontrollers with digital-power and motor-control Discovery Kits as well as including new firmware examples in the latest STM32CubeG4 software package (v 1.1.0).

The B-G474E-DPOW1 Discovery Kit:

  • Contains a STM32G474RE MCU, a buck-boost converter with on-board resistive loads, a high-brightness RGB LED controller, LEDs and buttons, flexible power and data connections and debugging support
  • Is a complete reference design for electronic speed control (ESC) for 3-phase brushless BLDC and PMSM motors up to 40A
  • Has a 3-phase motor-driver stage with STripFET F7 power MOSFETs, controlling either sans sensor field-oriented control (FOC) or six-step commutation
  • Includes electrical and thermal protection, interlocking high-side/low-side drivers, and support for motor sensors and three-shunt current sensing  

The B-G474E-DPOW1 digital-power Discovery Kit is $59.00 and the B-G431B-ESC1 for electronic speed control is $18.00. They are both available on or by distributors.
