Usage of CPU Pins 

Almost all pins of the i.MX RT1052 MCU are directly available on the SODIMM expansion connector. 

In a few cases are pins used for dedicated functionality like the Ethernet interface, EcoXiP interface 

and on-board SDRAM. These pins are not available on the SODIMM expansion connector. The table 

below lists all pins and their possible restrictions. 
Before using a signal, make sure usage does nto collide with functions on the 

iMX OEM Carrier Board

.
