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
