产品概述
描述
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.
