• LinkIt 7697 uses the MediaTek MT7697, a highly integrated single chip which features an application processor, a low power 1x1 11n single-band Wi-Fi subsystem, a Bluetooth subsystem, and a Power Management Unit. The application processor subsystem contains ARM Cortex-M4F MCU. It also includes many peripherals, including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC.
• For programming, you can program the board with the native LinkIt SDK using GCC, IAR embedded workbench, or KEIL uVision. In order to make it easier to use, LinkIt 7697 also provides a porting layer to the popular Arduino IDE - so that you can use your existing Arduino sketches and peripheral driver libraries.
• If comparing with Arduino UNO, you will find that the LinkIt 7697 is more powerful as it can run more complicated and store larger program, IoT application friendly and cost effective, you can even plug it into a breadboard directly and start your IoT project right away.
