永磁同步电机开发板选择

Other Parts Discussed in Thread: LAUNCHXL-F28069M, BOOSTXL-DRV8301, DRV8301-69M-KIT, DRV8301, TMS320F28069M

各位好:

   我是新手。现在想买TI的DSP板来做无传感器永磁同步电机的控制。有两个开发板,一个是www.ti.com.cn/.../launchxl-f28069mLP69M-1DRV-BNDL:LAUNCHXL-F28069M + BOOSTXL-DRV8301 bundle,DSP控制板和驱动板,73.99美元。

另一个是www.ti.com.cn/.../drv8301-69m-kit,器件型号是DRV8301-69M-KIT:Three Phase BLDC & PMSM Motor Kit with DRV8301 and InstaSPIN-enabled Piccolo TMS320F28069M MCU,299美元。

想问下相同的控制板和驱动板,为什么下面的比上面的贵得多,实际上有什么区别吗?

还请各位指教下,谢谢!
