LinkIt Smart 7688 Duo
The LinkIt Smart 7688 Duo development board is powered by the same MT7688AN SOC as the
LinkIt Smart 7688, but includes an ATmega32U4 MCU. This supports additional features including
Analog I/O support and Arduino IDE support. The board’s functionality is therefore a combination
of that provided by the two chipsets: Wi-Fi and Ethernet are supported through OpenWrt Linux on
the MT7688AN SOC, and various peripheral supported through Arduino on the ATmega32U4
microcontroller.
