New multicopter power distribution board+Buck regulator+Current/Voltage sensor

Hi guys,

I'm thinking over new multicopter power distribution board which will integrate also 4 current sensing shunts, two dual current/voltage/power sensors, a 42 Vin 3A DC-DC Buck regulator. The current,voltage and power measurements will be carried out over I2C interface. I think it's time to place aside the analogue measurements as there are a lot of clever ICs for the purpose.

Some explanations:

1. R1-R4 are 4 current shunts. Each of them can handle 60A...or even more, but some more thermal researches should be done;

2. US1 and US2 are dual current/voltage/power sensors with I2C interface;

3. U6 and surrounding passive components are the DC-DC Buck regulator;

4. The PCB is 6 Oz double sided with glued heat sink ( optional...if needed ) on the bottom layer.

As this is just a preliminary idea, I'd like to know your pro and cons about the design.

Best regards

BE Tech Club Kickstarter: Almost done!

Hello DIY Droners! My Name is Tim Vrakas, and I'm a student at Brookfield East High School. I'm working with my friends raise money for the BEHS Technology and Engineering Club. Some of you might have seen my previous post announcing the start of our kick starter, and DIY Drones was one of our biggest supporters so far. we have 11 days left, and a long way to go, but with your support I believe we can make it.

As you can see in our kick-starter video above, one of our biggest projects to date is our 3DR Quad. We also are working on a new fixed wing 3D imaging project. These projects have helped to build student understanding of a variety of topics. We have designed 3D printed frame parts, Laid out PCBs, and Programmed Python scripts. The Open Source properties of our drone is very helpful when it come to educating, because even the most complex system is understandable down to the simplest level. We need funding in order to continue with our work and broaden our influence on students who would otherwise not be exposed to STEM ideas.

We need the support of helpful communities like this one to support education of youth about the fields and hobbies that interest us. I hope that with you help we can further the education of our students. The DIY Drones Community needs more youth members in my opinion. (Let's just make sure they know how to fly first!)

Thanks for the Support!
