Product details

Overview

STEVAL-GMBL02V1 from STMicroelectronics is a reference design kit for triple-axis gimbal controller applications in drones and handheld cameras, featuring an STM32F303RE ARM® Cortex®-M4 MCU running field-oriented control (FOC) algorithms, three STSPIN233 three-phase motor drivers, 6.0–8.4 V operation (2S LiPo), 1.3 A_RMS per motor, and on-board LSM6DSL inertial measurement unit.

For engineers reviewing the STEVAL-GMBL02V1 datasheet, STEVAL-GMBL02V1 pinout, STEVAL-GMBL02V1 application, or STEVAL-GMBL02V1 equivalent, this kit supports real-time USB data exchange, SWD debugging via STEVAL-UKI001V1 adapter, PWM/ADC position sensor inputs, and hardware-level overvoltage, polarity inversion, thermal, and short-circuit protection.

Technical Context

The kit implements closed-loop FOC for three PMSM motors using a single STM32F303RE MCU with integrated DSP and FPU, supporting both sensor-based (PWM/analog) and sensorless open-loop control. Motor current sensing uses a triple single-shunt topology with STSPIN233 drivers providing EN/OC fault signaling and non-dissipative overcurrent protection.

System-level timing and stabilization rely on the on-board LSM6DSL IMU (6-axis) for frame-level orientation feedback, while external SPI/I2C IMUs can be connected for camera-axis compensation. Power management includes LD39050PU33R and LD1117S50TR LDOs, plus hardware polarity inversion and overvoltage protection up to 11 V.

FAQ

Does STEVAL-GMBL02V1 support sensorless FOC?

Yes. The STM32F303RE MCU implements open-loop sensorless FOC using back-EMF estimation, in addition to sensor-based FOC with PWM or analog position inputs. ST's Motor Control SDK v5.x provides validated firmware libraries for both modes, with real-time tuning via USB.

What motor types and configurations are supported?

The board drives three-phase surface-mounted or interior permanent magnet synchronous motors (PMSMs) with rated voltages between 6.0 V and 8.4 V. Each STSPIN233 channel supports 1.3 A_RMS continuous output, and the PCB layout accommodates standard 3-wire BLDC/PMSM connections with isolated sense resistors.

Can external IMUs be used alongside the on-board LSM6DSL?

Yes. The board provides dedicated SPI and I²C headers (CN8, CN10) for connecting external IMUs-such as the LSM9DS1 or ICM-20689-to enable camera-axis inertial feedback independent of the gimbal frame. Firmware supports time-synchronized dual-IMU fusion.

Is STEVAL-UKI001V1 included with the kit?

No. STEVAL-UKI001V1 is a separate ST-LINK/V2-1-based SWD debug adapter sold independently. The STEVAL-GMBL02V1 board includes a 10-pin SWD header (CN13) and is fully compatible with STEVAL-UKI001V1 or any standard ARM SWD debugger supporting 3.3 V I/O levels.
