Hexapod v2 using Linkit 7697
This is a Hexapod project.

* **Remote control** is done via `BLE` of `Linkit 7697`
* It has 6 legs, each leg has 3 joint. So there are total `18` **Servo motors** (TowerPro `MG92B`)
* Linkt 7697 dont have so many **PWM control**, so NXP `PCA9865` x 2 are used to control these servo motors
* Linkt 7697 dont have so many **PWM control**, so NXP `PCA9685` x 2 are used to control these servo motors
* **Power** comes from a `2S Lipo battery (7.4v)`. Also 7 x `mini360 DC-DC` step down voltage regulator are used. One to provide `5V` to Linkit 7697, The other six to provide `6V` to each legs (1 mini360 serve 3 servo)
* The **body** is 3D printed PLA. I use `Prusa i3 MK2S`, a really good 3D printer.
* Everything (3D STL, PCB schematic, 7697 source code) are included in the project under **GPL license**, Happy making!
