This document describes operation of STM 330, STM 331U, 331C, STM 332U, STM 333U
modules with their built-in firmware.
If you want to write own firmware running on the integrated micro controller or need more
detailed information on the Dolphin core please also refer to Dolphin Core Description and
Dolphin API Documentation at: http://www.enocean.com/en/knowledge-base/
If you want to connect other generic sensors to STM 33x (former STM 310 applications),
you can download STEMSEN Software from following link:
