### evelopment Environments <a href="#linkit7697-developmentguideforarduinoide-developmentenvironments" id="linkit7697-developmentguideforarduinoide-developmentenvironments"></a>

There are two software development environments available to LinkIt 7697 HDK.

**Arduino IDE**

A board package for the popular [Arduino IDE](https://www.arduino.cc/) is provided for convenience - so that you can use your existing Arduino sketches and peripheral driver libraries with some modifications, while having access to the onboard Wi-Fi and Bluetooth Low Energy features.

To develop with Arduino IDE, start with the[ Arduino IDE setup page](https://docs.labs.mediatek.com/resource/linkit7697-arduino/en/environment-setup/setup-arduino-ide).

**LinkIt SDK for RTOS**

You can also program the board with the native LinkIt SDK for RTOS using GCC and accompanied flash tool.

LinkIt SDK also supports IAR embedded workbench and Keil µVision IDE. You'll need a hardware debugger such as J-Link to program the board through SWD interface.

To develop with LinkIt SDK, you'll need LinkIt SDK v4.3 or later. Visit the [MT7697 resource page](https://docs.labs.mediatek.com/resource/mt7687-mt7697/en/get-started) for details.
