STEVAL-GMBL02V1

STEVAL-GMBL02V1 Data brief Reference design kit for Gimbal controller for drones and handheld applications Features Up to three-axis Gimbal controller. Compact (50 x 50 mm) design, suitable for mounting on: drones handheld cameras Three STSPIN233 low voltage three phase and three sense motor drivers. STM32F303RE microcontroller with ARM Cortex -M4 core able to simultaneously drive three PMSM motors: MCU runs a high efficiency field oriented control (FOC) algorithm compatible with the most common position sensors on Gimbal motors (PWM or analogic inputs) compatible with open loop sensorless algorithm Operating voltage from 6.0 V to 8.4 V (2 LiPo batteries). maximum output current 1.3 A . RMS Protection mechanisms: triple single shunt current sensing network non-dissipative overcurrent protection short-circuit protection thermal shutdown hardware overvoltage and polarity inversion protection Measurement units: on-board inertial measurement unit LSM6DSL (frame IMU) Product summary compatible with external SPI/I2C inertial measurement units (camera IMU) Reference design kit STEVAL- Interfaces: for Gimbal controller GMBL02V1 STEVAL-UKI001V1 Serial Wire Debug (SWD) board with cable Mixed signal MCU ARM Cortex-M4 core STM32F303RE USB connector for real-time data communication with DSP and FPU three connectors for Pitch, Roll and Tilt axis target angle inputs (PWM mode) Low voltage three phase and three STSPIN233 one channel DAC output and one GPIO test point for debugging purpose sense motor driver 2 Kbit serial IC bus EEPROM for data storage WEEE and RoHS compliant Description The STEVAL-GMBL02V1 reference design kit is a complete triple motor field-oriented control (FOC) demonstration and evaluation platform as well as an integrated environment for three axis Gimbal controller applications in the 6.0 V to 8.4 V bus DC voltage range (2 LiPo batteries), which you can increase up to 11 V with a maximum output current of 1.3 A for each motor drive. The design features the STM32F303RE microcontroller with ARM Cortex -M4 32- bit core and the STSPIN233 low voltage three phase and three sense motor driver. The kit is equipped with a USB interface for real-time data exchange and includes an STEVAL-UKI001V1 ST-LINK adapter for serial wire debug (SWD) and corresponding cable. If you mount the STEVAL-UKI001V1 on the ST-LINK/V2-1 debugging section of an STM32 Nucleo-64 board, you can program and debug the STM32F303RE microcontroller with a compatible toolset via USB.
