What are Open Hardware Designs? However, from the very beginning I had an interesting issue with this power module. Ignore temporary files. Flight logs fmuv5 open hardware design use also handy when asking for help in the official PX4 support channels. Packages 0 No packages published. Because of their specifications, they are even more convenient for external devices that consume relatively higher power. Designs are usually specified in the form of schematics that show all included components CPU, sensors, etc.

It was just that, for some reason, the flight controller was apparently getting erroneous readings from the current and voltage sensors in the power module.

I got rid of the adapter cable and did a flight test again. The flight time improved to around minutes, before the warning signal sounded again. I was also told that, apparently for a 3S LiPo battery, a current of around 15A was normally expected for the kind of quadrotor configuration I had, instead of the 22A I was getting in the flight logs. From past logs from other similar quadrotors, I found that currents between 13A to 15A were typical. It was suggested Fmuv5 Open Hardware Design Github that I try using a LiPo battery with more cells, so I did tests with 4S batteries; the drone flew well but with a bit of oscillation.

I always tend to use 3S batteries with quadrotors of this size and configuration, anyway. This default configuration causes the flight controller to do conservative estimates of the remaining battery power and available flight time.

So, after tweaking these battery parameters a bit, the flight time rose a little more. I had never previously encountered any issue like this before, and it took me some days to understand what was happening. As you know, failure is a master that treats roughly but teaches well. Figure 9 shows the quadrotor during a flight test. Both outputs are convenient to power external devices, such as off-board sensors and actuators, cameras, wireless transceivers and companion computers.

Because of their specifications, they are even more convenient for external devices that consume relatively higher power. According to the manufacturer, it accurately measures voltage and current in real time, and uses CAN bus communication and the UAV CAN protocol to send power consumption data to the core.

The manufacturer says its ITT algorithm corrects measurement errors caused by impedance changes at different operating temperatures, to maintain consistent high-precision voltage and current measurements. These can be present in regular power modules that feed the flight controller with voltage and current measurements in analog format.

These data are then passed to the flight Fmuv5 Open Hardware Design Engine controller. The PMU can accurately measure currents between A. The kit I received came well packed in a fine box. When powered, both the flight controller core and GNSS module emit an elegant, halo-like status light surrounding their bodies. This highly reduces the probability of a crash due to multiple-sensor failure. This kind of reliability is important, for instance when your aircraft carries expensive remote sensing equipment, such as professional video cameras, high-end LIDARs or high-resolution thermal cameras.

The configuration process is equally easy with both platforms. But whether you work with drones professionally, or you are a drone enthusiast always eager to try new things, perhaps you should take a serious look at the V5 Plus.

It could be just the type of reliable flight controller you are looking for. Analog Devices www. Raul Alvarez Torrico has a B. In his spare time, he likes to experiment with wireless sensor networks, robotics and artificial intelligence. You may contact him at [email protected].
