If you’ve been paying attention to what what’s going on in the hobby electronics world, you’ve undoubtedly heard of the ESP8266 module. This little guy was meant as a way to add WiFi to other devices, but has the capability to do so much more. Because of these capabilities, Pesky Products decided to put it on a tiny board (.71″ x 1.22″) in a configuration suitable for controlling a small quadcopter.
According to the product writeup, the easiest way to get this flight controller working is to solder a normal receiver onto the board and control it as you would any other UAV. On the other hand, since the ESP8266 module has WiFi capability built-in, in theory this would allow one to control your multicopter with another WiFi enabled device.
For that matter, even though this is advertised as a flight controller and can be programmed as such upon request, the board can easily be used in more general robotics applications. With an onboard processor, sensors, and GPIO pins, there is really no limit to the applications for something like this.
Other non-quadcopter possibilities aside, check out the video below to see it in action.
