Linkit Smart 7688 {#linkit}
=================
The Linkit Smart 7688 is based on the MediaTek MT7688 system on a chip, which
includes a MIPS 24KEc 580 MHz processor and 128 megabytes of RAM.
Features:
* 20 GPIO pins
* 4 PWM pins
* 3 UART ports
* 1 SPI master port
* 1 SPI slave port (not supported by libmraa)
* 1 I2C port
* 1 I2S port (not supported by libmraa)
