Description

The STEVAL-GMBL02V1 reference design kit is a complete triple motor field-oriented control (FOC) demonstration and evaluation platform. The kit is as an integrated environment for three axis Gimbal controller applications in the 6.0 V to 8.4 VDC bus 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 STEVAL-GMBL02V1 is equipped with a USB interface for real-time data exchange. The kit 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.

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.
