Pin Descriptions

• If using Ethernet, do not use pin67, pin56, pin41, pin52, pin63, and pin40.

• If using SDMMC2, do not use pin11, pin48, and pin59.

• Depending on the CubeNode version, the IMU may not be available.

• Do not use pin12, pin85-pin95, pin98-pin100, pin103-pin105, pin108, and pin109. They are reserved for future use.
