  • And buried in the top layer we find another control board, functionally identical to the one we dug up in the original Echo.

  • National Semiconductor LP55231 Programmable 9-Output LED Driver (x4)

  • Texas Instruments TLV320ADC3101 92dB SNR Low-Power Stereo ADC (x4)

  • Diodes Incorporated LMV321SE Single Operational Amplifier

  • Texas Instruments SN74LVC74A Dual Positive-Edge-Triggered D-Type Flip-Flops

  • Diodes Incorporated 74LVC1G14 Schmitt Trigger Inverter

  • Diodes Incorporated 74LVC1G125 Single Buffer (x2)

In der obersten Ebene befindet sich eine weitere Steuerplatine, die funktional identisch mit der ist, welche wir aus dem original Echo ausgebaut haben.
