  INMP441 Breakout Module - Fusion 360 Electronics / Eagle library

  Target: common purple/green INMP441 I2S MEMS microphone breakout
  (the one sold on AliExpress/Amazon with a 1x6 2.54 mm pin header).

  Nominal module size: 15.0 x 10.5 mm, pin header on one long edge.
  Pin order (from the silkscreen of the most common variant):
      1 = SCK  (I2S bit clock)
      2 = SD   (I2S data out)
      3 = WS   (I2S word select / LRCLK)
      4 = L/R  (channel select: GND = left, VDD = right)
      5 = GND
      6 = VDD  (1.8 - 3.3 V)

  Footprint: 1x6 through-hole header, 2.54 mm pitch, drill 1.0 mm,
  pad 1.8 mm. Module outline drawn on tPlace (layer 21) and tDocu
  (layer 51), with a keepout around the MEMS port hole.
