一、电路设计

硬件组成：

Arduini Nan
ESP8266
MPU6050 模块
有刷电机
螺旋桨
电池包
Si2302场效应管
无人机架

ESP8266模块

为了与无人机通信，我们需要蓝牙或WIFI连接，所以我们使用ESP8266 Wi-Fi模块，因为它有内置的Wi-Fi，我们可以使用它进行通信。

ESP8266开源、互动、可编程、低成本、简单、智能、最低成本的Wi-Fi硬件。

至于无人机的飞行范围。测试已经得到了范围大约是70米，使用三星手机充当WiFi热点和远程控制器。

MPU6050

MPU6050 IMU，一个低成本的设备，包含陀螺仪和加速计。

我们将使用MPU-6050和ESP8266模块来做一个无人机。
