Power System Wiring
This page describes how to create the power wiring. To complete this section, you need:
- Power regulator for NUC (Parts List, ID 13)
- Power case (Parts List, ID 21)
- NUC DC power connector (Parts List, ID 22)
- XT30 power connector (Parts List, ID 23)
- Screws for power box mounting (Parts List, ID 24)
- Screws for power box top lid mounting (Parts List, ID 25)
- In order to power up the NUC computer, 12V with 3A (around 36W) are needed as benchmarked here. We use the XT30 power connector to get 25V (~up to 10A) battery power.
This is then fed it into the power regulator that outputs 10A at 12V via a right angle DC plug (5.5mm outer diameter, 2.5mm inner diameter).
The assembled power module after some soldering and insulation is shown below:
After that, connect the TX30 to the port on the drone labelled as [1] in the figure below. Check whether the DC plug is outputting 12V using a multimeter (this is important, otherwise your NUC may be damaged!).
- You can print the 3-D models below for the power case (Parts List, ID 21). There are three parts: power box, bottom fix, and top lid.
First, place the power box in front of the MAV and align the two extruded circles into the holes on it.
Second, using the bottom fix plate and two M3*12 screws, tighten up the power box on the drone.
Third, put the power module and the other USB cables/FTDI modules in the box as much as cleanly possible. The figure below shows an example of how to put everything inside, pulling out only the necessary connectors.
Finally, mount the top lid using four M2.5 screws.
Congratulations! You have just finished building your own MAV. Try to fly manually with the lightbridge 2.
If you have flying issues, such as drifting or signal compass errors, try to fix them through an IMU calibration procedure (DJI guide, calibration tips).
Once you are satisfied with the settings and performance, please proceed to setting up the software packages.
