Pixhawk PX4 PIX 2.4.8 Flight Controller 32 Bit Flight Control Board I2C Splitter Expand Module Buzzer Safety Switch 4GB SD Card for FPV Quadcopter Multirotor Drone

Excellent autonomous functionality, you can accomplish almost anything with these controllers. Lots of excellent tutorials available on YouTube. Well packaged and came with lots of extra accessories. Recommended

It's a pixhawk flight controller! The controller itself works great, the plugs and cables included are okay. That being said I have 2 complaints. First, the controller isn't well centered in the plastic enclosure on mine which made plugging things like my GPS module in to be a pain. The second complaint has to do with the buzzer, it's snap together design is extremely flimsy, resulting in it seperating from the base it becoming nuisance prone to popping apart (nothing some electrical tape couldn't solve but it doesn't change the fact. I would also add that the power button, though nice is kind of hard to mount. It's just heatshrinked to the end of the wire. You should also be aware that this kit doesn't include the power adapter needed to power the pixhawk. If your building a drone, this kit is cheaper than buying all the parts if you don't need/want them. I would look up: "Pixhawk Power Module 30V" and you'll find they are usually around $9.99 They plug into the 'power' port and power the pixhawk plus most of the things you'll plug into it.

All good

Bad quality, faulty sensors, bad flash memory, I guess you get what you pay for
