The EVLSPIN32G0A1 evaluation board from STMicroelectronics provides a hardware platform for assessing the STSPIN32G0A1 integrated motor-control system in three-phase brushless dc (BLDC) motor applications.
The board operates from a supply range of 7V to 45V, and includes a power stage built from six STD140N6F7 MOSFETs which conduct up to 15Arms of continuous current. A three-shunt sensing topology is implemented to support high-performance field-oriented control and 6-step drive algorithms.
The board integrates voltage monitoring, PCB temperature sensing, an over-current comparator and under-voltage checks on driver supplies, enabling evaluation of the protection functions without external hardware. Digital Hall sensor and encoder inputs are provided for rotor position feedback, and bus voltage measurement is available for control loop implementation.
The onboard regulators supply 3.3V and 12V rails for the integrated microcontroller and gate driver.
An embedded ST-LINK/V2-1 interface allows programming, debugging and UART communication through a Virtual COM port. User inputs include buttons and a potentiometer for speed and parameter adjustment during motor testing. When used with the STM32 Motor Control SDK, the board supports development and verification of control firmware for power tools, small appliances, fans, robotics and other low- to mid-power BLDC motor drives.
