  • The B-G431B-ESC1 Discovery kit is based on the STM32G431CB microcontroller, the L6387 driver and STL180N6F7 power MOSFETs. It is composed of a main power board, and a daughterboard with embedded ST-LINK/V2-1. It is an electronic speed controller (ESC), designed to drive a single 3-phase brushless motor (BLDC/PMSM), performing both sensorless FOC algorithm and 6-step control with a speed regulation, and an active braking function algorithm. The ST sensorless FOC algorithm ensures longer flight times and an optimal dynamic performance. This unit accepts command signal from an external unit for driving and monitoring, for instance a flight control board or equivalent. For this purpose, several communication bus interfaces (UART, CAN, PWM channel) are present. A potentiometer and a user button are available for user application. The daughterboard includes a 5 V battery eliminator circuit (BEC), and the main board embeds an overcurrent/overvoltage and thermal protection circuit. The form factor makes it suitable for small and very light R/C vehicles (FPV race drone) and the motor current capability fits the power requirement of big vehicles, for instance a prosumer drone.

    Key Features

    • Full reference design for electronic speed controller capable of both sensorless FOC and 6-step algorithm
    • Designed for drones with up to 6S LiPo battery pack or equivalent suitable DC supply
    • 3-phase driver board for BLDC/PMSM motors with discrete N-channel 60 V, 120 A STripFET F7 power MOSFETs
    • STM32G431CB Arm® Cortex®-M4 32-bit MCU, 213 DMIPS, 128 Kbytes of Flash memory, 32 Kbytes of SRAM, analog rich, math accelerator
    • On-board ST-LINK/V2-1 debugger/programmer detachable from the main board
    • Output peak motor current (maximum peak current tested with propeller to have an air-forced cooling): 40 A
    • Designed with SMD ceramic capacitors with very low profile
    • BEC available through the daughterboard (5 V for external board supply, for example a flight control board)
    • Support for motor sensors (Hall or encoder)
    • Supported by ST Motor Control Software Development Kit (SDK) with ST Motor profiler
    • 3-shunt mode supported for motor current sensing
    • L6387 High voltage high and low-side driver with integrated interlocking function

    • ESC ready for communication with any standard flight control unit (FCU): PWM/CAN/UART
    • Potentiometer and user button available on daughterboard
    • Two user LEDs: one green LED for 3.3 V level, and one red LED configurable by the user
    • Target applications: motor driving for R/C vehicles, UAV drone, electric car or boat
    • PCB type and size:
      • FR-4 PCB material
      • 8-layer layout
