Figure 3 display the highlighted 9 pin connector J202 on bottom side of SoM_IoT_1V2 printed circuit board. This connector allocate the large-scale integrated circuit R-IN32M3-EC with external SPI and additional SYNC signals. Furthermore the power supply pins VCC33 and GROUND are connected on J202.
Pin 1 (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 15V DC to 3,6V 45V DC.
Note: Higher voltage (above 3.6V DC) at power supply pins may cause damage this module!
