Just received my Odroid W board from here.
It’s incredibly small:
In the end I decided I’ll use this instead of the standard raspberry pi.
I’m working on a new design right now that will include vibration damping at the motor mount and the Odroid W.
The new components are:
- Blue Wonder 1300Kv motors, as they are half the size of the Suppo 2208 I use currently – 24g vs 45g. 80 grams saved just from these
- 9×4.7 CF props
- The tiny Odroid W. This will allow me to design a smaller case. It also contains 2 ADC inputs – perfect for the voltage/current sensors. It’s such a pity that it’s discontinued.
- 4 new ESCs – They are 6g each without the shrink wrap and work perfectly when flashed with bl-heli. So 24 total compared to 50 total for the Quattro ESC I use now.
- A new sonar – SRF02 – Should have better range, is smaller and doesn’t require 2 GPIOs and accurate timing as it’s i2c and does the range computation itself.
- A 5A switching BEC.
- The Drotek IMU
In total I think I can save 200 grams. The new quad will total at around 550-600g – perfect for the blue wonder motors that have a total max thrust of 1800-2000g.
