MediaTek LinkIt™ Smart 7688 User Manual
1.4. LinkIt Smart 7688 Duo
LinkIt Smart 7688 Duo is powered by the same MT7688AN SOC as LinkIt Smart
7688, but adds an extra ATMega32U4 on the development board. This supports
additional features including Analog I/O support and Arduino IDE support.
The board’s functionality thus becomes a combination of both chipsets: Wi-
Fi and Ethernet support through OpenWRT Linux on MT7688AN SOC, and various
kinds of peripheral support through Arduino on ATMega32U4 microcontroller.
1.4.1. Key Features
Linkit Smart 7688 Duos key features include the following:
Wi-Fi 1T1R 802.11 b/g/n (2.4G)
Pin-out for GPIO, I2C, I2S, SPI, SPIS, UART, PWM and Ethernet Port
580 MHz MIPS CPU
32MB flash and 128MB DDR2 RAM
Built-in USB host and Micro SD slot
Arduino support (ATmega32U4)
LinkIt Smart 7688 Duo is shown in Figure 6.
