  • We've got part two of the power supply, the Stargate Halo power distribution ring, on the hook.

  • The capacitor-studded side of our intergalactic power supply board is home to a STMicroelectronics STM32L051C8T7 ultra-low-power ARM MCU.

  • And on the other side we find:

  • International Rectifier PowlRaudio 98-0431 audio amplifier

  • Cirrus Logic CS4350 stereo DAC w/ intergrated PLL

  • And around the perimeter, seven Analog Devices SSM3515B audio amplifiers—looks like these are the individual amps for the tweeters!

  • Maxim Integrated MAX9938 and Texas Instruments INA210 current sense amplifier

  • Texas Instruments TPS54560 5 A step down converter

我们已经拿到了第二部分的电源，在钩子上的是一个光环里的星际之门配电环。

我们的星际风电源板电容密集的一侧安了一颗意法半导体的STM32L051C8T7超低功耗ARM微控制单元。

在另外一面，我们发现了：

国际整流器（IR）公司的PowlRaudio 98-0431音频放大器

4350C Y01742 TWN

并且在周围，有七个亚德诺半导体（ADI）公司的SSM35158音频放大器 - 看起来像是这些高频扬声器的独立放大器！
