The possibility to connect expansion boards enables a wide range of upgrades, such as other wireless standards, sensors or other peripherals. The boards can be connected via the two 20-pin headers. These headers provide several communication interfaces to the main-processor, such as I2C or SPI.

The Bluetooth expansion board has been designed to make it possible to communicate wireless with a PC or the joystick.


The Debug board makes it possible to power the quadcopter with an external power supply. This board can also be used to program the main-processor and the four motor controlling microcontrollers.
