LinkIt 7697 ( Linkit 7697 物聯網裝置開發板 ) is a co-design product by Seeed Studio and MediaTek. As the latest member of the LinkIt family, it uses the MediaTek MT7697 SoC and aims at providing lightweight IoT solution. It may reminds you of LinkIt Smart 7688/Duo, another development board which released in 2015. Both of them are born for IoT however they are quite different.
The chipset of LinkIt 7697 is MT7697, a highly integrated single chip which features an application processor, a low power 1×1 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.
Linkit 7697 物聯網裝置開發板 For programming
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.
Grove Thumb Joystick 搖桿模組是Grove兼容模組，與PS2（PlayStation 2）控制器上的“模擬”操縱桿非常相似。兩個方向的移動將輸出不同的模擬信號，因為它們實際上是兩個電位器。電阻器每個〜10K。操縱桿還有一個可用於特殊應用的按鈕。當模組處於工作模式時，輸出代表兩個方向的兩個模擬值。該值在一個較小的範圍（例如200〜700）的限制相比於正常操縱桿即圍繞1023當按鈕被按下時，使得MCU可以檢測按壓的動作。
