The EVSPIN32F02Q1S1 board is a 3-phase complete inverter based on the STSPIN32F0251 controller, which embeds a 3‑phase 250 V gate driver and a Cortex®-M0 STM32 MCU. The power stage features STD17NF25 MOSFETS, but can be populated with any IGBT or Power MOSFET in DPAK or powerFLAT 6x5 package.

The board has a single-shunt sensing topology, and both sensored and sensorless FOC and 6‑step control algorithms can be implemented. This allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors.

The evaluation board is compatible with a wide range input voltage from 15 VAC (20 VDC) to 120 VAC (170 VDC), and includes a power supply stage with the VIPER013BLS in buck configuration to generate +15 V and +3.3 V supply voltage required by the application.

Debug and configuration of FW can be performed with standard STM32 tools through the detachable ST-LINK‑debugger. SWD and UART TX‑RX connectors are also available.
