STEVAL-PTOOL1V1

TEVAL-PTOOL1V1 compact 70mm x 30mm reference design board is tailored for low voltage power tools driven by 3-phase brushless motors, supplied by 2S to 6S batteries. The design is based on the STSPIN32F0B controller and STL180N6F7 (or STL220N6F7) Power MOSFET. The board is ready for sensorelss and sensored FOC, and can be configured for six-step sensorless control through available BEMF sensing circuitry. The accompanying six-step STSW-PTOOL1V1 firmware uses position feedback from Hall effect sensors, with debugging and programming capability available through the SWD interface and the direct firmware update feature.
