有什么直截了当的方法来为先锋提供3.6V电源？

有没有一种直截了当的方法来为先锋提供3.6V电源？我尝试过多种方法，但没有多少成功。应用3.6V到VIN似乎毫无用处。通过USB端口应用它并不能提供足够的电源，所以其中一盏灯亮起，但没有做太多的事情。它似乎通过3.3V-EXT作品应用3.3V-3.4V，但机载保护电路关闭板时，我得到约3.47伏（使用台式电源测试）。
有没有直接向3.6V供电的电路板，而不需要外部调节电路？

  Is there a straight-forward way to power the Pioneer from a 3.6V power supply?  I have tried multiple methods of doing so without much success... Applying 3.6V to Vin seems to do nothing.  Applying it through the USB port does not provide enough power and so one of the lights dimly lights up, but doesn't do much else.  It seems applying 3.3V-3.4V through the 3.3V EXT works, but the onboard protection circuitry shuts off the board when I get to about 3.47V (tested using a bench power supply).
