In following figures are all 27 respectively 45 available pins displayed and marked with colored header for clear pin identification. All signal lines (Pin 3 to 13 and pin 15 to 18) of connector J202 and J302 respectively include a series resistor with 22Ω resistance for impedance matching and to protect internal circuits of R-IN32M3-EC. For SoM_IoT_2V0 the pins 19 to 36 are also with series resistors prepared.

 

For full description of register settings and mode control verify the datasheet of R-IN32M3 series (R-IN32M3 Series, User’s Manual: Peripheral Modules, Document Number: R18UZ0007EJ1000, Issue date: Feb 28, 2017).
