Elle0 Paparazzi UAV Autopilot Introduction

Hi Everyone,

I made a new video describing the details of the Elle0 Paparazzi UAV autopilot. Elle0 is now available for purchase in the 1BitSquared store together with the G0 companion GPS receiver. In the video I go through and describe every IO pin as well as some of the design differences to the Lisa/MX Autopilot that I designed before the Elle0. Additionally, I describe how you can add a battery voltage monitor to your Elle0 using a voltage divider circuit, and how it fits together with the new G0 GPS receiver.

I hope this video is helpful. If you think so too please let me know in the YouTube comments. I am planning to make many more videos describing different aspects of Paparazzi UAV, not only hardware but also flight videos and Paparazzi software tutorials and tips. If you think it will be useful for you make sure to subscribe and tell me in the comments what you would like to see.

Also, check out the Elle0 paparazzi wiki page for more information about the autopilot itself and diagrams of the system. Additionally to the Elle0 and G0 boards we have also released a matching R0 radio board and UU0 UART to USB adapter boards. We will be making videos describing more parts of the modular system we are working on soon. Whereas the Elle0 and G0 are already in stock, the R0 & UU0 are available for Pre-Order in our US store.

Cheers, and successful flights,

Esden and the 1BitSquared team

I am very interested in this product. Can you please explain how is the performance of GPS modes ? How about automated flights compared to apm. I want to build another quad and this flight controller seems very promising.

I was just reading the paparazzi wiki and I found a lot of good docs If I wanted to adopt the platform and create an aircraft. What I didn't find so easily available is why I would adopt Papparazzi. What are the features that separate Papparazzi from other autopilots? Why would I choose to stop using APM/Dronecode on my drones given now that paparazzi has been ported to a pixhawk?

Looks good. I like the simplicity. However the external voltage divider to measure battery voltage looks like a hack. On this type of board, I have used a fixed onboard voltage divider capable of handling 6S. This will handle most use cases. The resolution of the stm32f4 A2D is quite good enough for dow to 2S. For use outside that range you will only need to replace one resistor anyway.

Presumably this board Like many others out there could run Ardupilot as well. The only issue being onboard logging which is not essential. Can be done by telemetry

@earthpatrol Thanks! I am glad it works well. Thanks for your help with all the autonomous flight tests we did, locating issues and coming up with possible improvements regarding the G0 GPS design. It is interesting to see how physics is difficult to cheat when dealing with RF. You realize that size does matter when it comes to antennas. :)

The R0 and UU0 are well under way! I can't wait to make them available either. :)

Great job @esden. I really like how the GPS integrates with the Autopilot. I've also noticed better GPS performance when using the newer G0 design. The quality is top notch. Spoiler Alert: Can't wait to try the new telemetry modules as well.
