2.2 Pin out
The figure above shows the pin out of the STM 31x hardware. The pins are named accord-
ing to the naming of the EO3000I chip to simplify usage of the DOLPHIN API.
The table in section 2.3 shows the translation of hardware pins to a naming that fits the
functionality of the built-in firmware.
