Arduino STAR - OTTO

The Star Otto is the first Arduino board featuring the STM32F469 processor with WiFi.

The Arduino Star series of boards feature ST Microelectronics processors, and the first of the series is the Star Otto.  The Otto combines the power of the STM32F469 processor and an Espressif ESP8266 for WiFi, with several on-board peripherals, such as a micro-SD slot, connectors for a camera and an LCD, USB Host, headphone and speaker output, and an on-board stereo microphone.
