B-G431B-ESC1

B-G431B-ESC1 is a discovery kit with STM32G431CB MCU. It is based on the STM32G431CB MCU, 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 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 5V BEC and the main board embeds an OC/OV and thermal protection circuit.
