Teleduino IoT API for Arduino

I am interested in Arduino and IoT. Some time ago I visited Teleduino project page that looked really inteesting on this point of view. Teleduino converts en ethernet enabled Arduino into a tool for interacting with devices over the internet. It seemed that with this service I can easily turn an Arduino to an IoT device

GarrettCom Converter Teardown

The main components are BCM5325A2KQMG Ethernet switch, BCM5221A4KPTG Ethernet PHY, HFBR5961LZ fiber transceiver and LM2591HVT-3.3 simple switcher power supply. This looks like quite normal small Ethernet swich design. There is 5 port Ethernet switch IC handling copper ports directly and fiber through PHY IC. This device I opened was broken on power supply circuit. The
