=== Dedicated I2C ===
IGEP COM AQUILA uses I2C0 from 40 to 41 SODIMM lineswith 5K Pull up. These dedicated I2C lines IGEP COM AQUILA EXPANSION uses USB1 peripheral as USB 2.0 Host. SODIMM lines from 27 to 31 are USB dedicated lines. IGEP AQUILA EXPANSION Public Schematics adaptsSODIMM lines for an USB Type A receptacleshared with PMIC (0x2d address).
=== Optional I2C ===
IGEP COM AQUILA EXPANSION uses USB0 peripheral as USB 2.0 OTG. contains two optional I2c buses:*I2C1 from 44 and 47 SODIMM lines from 33 to 38 are USB dedicated lines. IGEP AQUILA EXPANSION Public Schematics adapts*I2C2 from 46 and 48 SODIMM lines for an USB Type mini AB receptacle.
=== I2C design notes===
* For USB I2C0 should be your default option, but it could be interesting use Optional I2Cs if your external peripheral need to use a huge transfer data lines: USB1 (USBH_DM (29) and USBH_DP (31)) and USB0 (USBOTG_DM (35) and USBOTG_DP (37))connection.**Maintain symmetry and isolate differential pairs from nearby signals and circuitry Optional I2Cs needs to be pulled up externally, 5K resistor tied to mantain the signal integrity3V3 must be necessary.
