3.2 Hardware pin out
The figure above shows the pin out of the STM 300 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 3.3 shows the translation of hardware pins to a naming that fits the
functionality of the built-in firmware. When writing own firmware based on the DOLPHIN
API please refer to the Dolphin Core Description and use this manual only for information
