ColibriBoard is the next generation, powerful and highly integrated flight controller for multi-rotor UAV. ColibriBoard offers impressive list of features, unmatched by any of the flight controllers that are currently on the market.
Colibri acts as a baseboard for the WandBoard system-on-a-module (www.wandboard.org), hence there are 2 CPUs at developer’s disposal:
The outside world connects to Colibri using SigmaDrone’s JSON RPC API, accessible over the WiFi hotspot exposed by Wandboard. The Cortex A9 relays the commands to the Cortex M4 via high-speed serial bus, thus giving the user powerful toolset to control the drone both in flight and at rest.
Just like any modern flight controller, Colibri has state of the art 9 DOF inertial measurement unit, with back-up gyroscope and accelerometer, and 2 pressure sensors. Additional sensors may be attached through the externally available SPI and I2C buses.
On board Colibri there is an uBlox LEA-6S GPS module with a patch antenna, but there is also an option for attaching an external antenna. The GPS module has a backup battery for fast re-sync after a power-cycle.
Colibri offers a rich list of options for attaching additional devices:
Colibri is an open source and open hardware project - no secrets, only solid engineering!
