3 FUNCTIONAL DESCRIPTION
3.1 Pin out
The figure above shows the pin out of the TCM 300x / TCM 320x hardware. The pins are
named according to the naming of the Dolphin chip to simplify usage of the DOLPHIN API.
The table in section 3.2 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
regarding the module hardware, such as pin out, layout recommendations, power supply
requirements, antenna options, and approvals.
