By now, the specs on the Samsung Galaxy Nexus are already publicly known, but what other magic is hiding within all the wires and circuitry? To find out, we've enlisted the help of developer Francois Simond (SuperCurio) to break down as many of the inner components of the Android 4.0-loaded device as possible. And while there isn't anything particularly earth-shattering revealed here, we at least have a better idea of the kind of wizardry taking place underneath that bedazzling HD display. Read on with us to learn all of the deliciously nerdy details.



Here are a few things we unearthed in the Galaxy Nexus:

Silicon

  • CPU: Texas Instruments OMAP4460, 2047.7 BogoMIPS
  • GPU: Imagination Technologies PowerVR SGX 540 (same as the Galaxy S and Nexus S, though this one uses a higher clock speed at 384MHz)
  • WiFi / Bluetooth module: Broadcom BCM4330 (same as in the Galaxy S II)
  • Audio codec: Texas Instruments TWL6040
  • HDMI: Silicon Image MHD SiI9234 transmitter over MHL (same as Infuse 4G and GSII)
  • USB Switch: Fairchild semiconductors fsa9480 (industry standard)
  • Framebuffer controller: Samsung S6E8AA0 MIPI LCD with Gamma correction driver

  • Geomagnetic sensor: Brand new tri-axial Yamaha YAS530
  • TouchScreen sensor: Melfas MMSxxx touchscreen
  • Optical / proximity sensor: GP2A (same as Galaxy S and Nexus S)
  • Barometric pressure sensor: BOSCH BMP180 (first of its kind in a smartphone)
  • Triaxial acceleration sensor: BOSCH BMA250(PDF)
  • Triple Axis MEMS Gyroscope: InvenSense MPU3050
  • Fuel Gauge (algorithm to track battery's state of charge): MAXIM MAX17040
Misc. internals
  • Facial recognition elements (Face Unlock): left eye, right eye, nose base, head, face
  • Available resolution for standard apps: 720 x 1184px
  • Refresh rate: 60Hz
  • LCD Density: 320
  • Default display color depth: 32bit
  • Camera uses OMAP Ducati Subsystem, on-screen preview size is 768 x 576
  • Linux kernel: 3.0.1 compiled for SMP with voluntary kernel preemption for best interactivity
  • Android ROM: version 4.0.1, built October 13, 2011
  • Device name: Maguro
  • Main input/output type supported: Headphone, Speaker, Microphone, Bluetooth, Voice, FM, S/PDIF over HDMI; USB Audio DAC (digital-to-audio converter with USB input and stereo outputs) should also be supported
