PiPilot
PiPilot lets you control a drone from a web browser. It's been designed to work with Raspberry Pi, hence its name. However, you can likely make it work with anything that has UART. It should be able to interface with any autopilot board capable of understanding the SBUS protocol.
The purpose of the project is to let the autopilot control the fundamental behavior of a drone, i.e., attitude using gyros and accelerometers, and provide functionality controlling velocity, altitude hold, and basic navigation using more sophisticated sensors. We're not there yet.
Inverter
Since SBUS, in reality, is inverted UART, you cannot connect the wires directly. You will need to build yourself an inverter.
Installation
$ pip install PiPilot
$ pipilot -n pipilot
