BLDC馬達控制板
The BLDC Motor Control Shield with TLE9879QXA40 for Arduino Uno makes it easy to control and drive a BLDC motor. It features an Infineon TLE9879QXA40, a single chip 3-Phase motor driver with integrated MOSFETs.
The shield can be controlled by a microcontroller via an SPI interface - here the Arduino Uno R3 is used as master. Both the shield and the Arduino board are connected via the pin headers.
Up to four shields can be stacked via the pin headers, to control up to four BLDC motors
