STMicroelectronics STEVAL-ESC002V1 Electronic Speed Controller Board

STMicroelectronics STEVAL-ESC002V1 Electronic Speed Controller Board is a very compact and ready to use Electronic Speed Controller (ESC) reference design. The board fits any small and light drone for racing or surveying purposes. It’s also highly suitable for any three-phase BLDC application requiring a small form factor, minimal BoM, and high-speed rotation performance. Together with the companion firmware package (STSW-ESC002V1), it represents a solution for sensorless voltage mode six-step driving.

The board includes the STSPIN32F0A advanced 3-phase brushless motor controller that embeds an STM32 Cortex®-M0® microcontroller, voltage regulators, signal conditioning circuitry and gate drivers in a small 7x7mm² QFN package. The power stage is based on the 2.8mΩ low resistance, high-speed TL140N6F7 MOSFETs, designed with STripFET™ F7 technology and able to deliver up to 20A of continuous current.
