Figure 10 display the highlighted 9 pin connector J301 on bottom side of SoM_IoT_1V2 2V0 printed circuit board. This connector allocate the large-scale integrated circuit With connector J301 are two 10BASE-T, 100BASE-TX/FX ethernet ports realized. The SoM-iRJ45 module includes the R-IN32M3-EC with external SPI and additional SYNC signals. Furthermore the power supply pins VCC33 and GROUND are connected on J202.Image RemovedEthernet Switch with additional TVS array connection for ESD and transient protection. Furthermore, the magnetic components for galvanic decoupling and signal integrity are offered too.

Image Added

Pin 37 (VCC33) and pin 2 (GND) should be connect with external DC voltage source. The SoM_iRJ45 is specified for an input voltage range of 3,0V DC to 3,6V DC.
