Electrical
CoreWii uses the SExI interface (Appendix A: SolderCore Expansion Interface) for
rapid integration into a hardware platform. The communications pins (I2C) are
taken to the appropriate SExI connector pins, as are the power rails.
There is an LED on the CoreWii module that can be controlled using the DIO line.
Table 1 details the pin configuration. CoreMag uses the 3V3 rail and not 5V.
The pull-up resistors, R1 and R2, are not fitted to the board by default. You will need
to fit both R1 and R2 if the external development platform does not provide I2C pull-
up resistors.
