Notes by BitCraze

  • There are 10 x 500mAh charger in there that can be soldered together as in the picture here. There is also a 4 x charger that is probably easier to use so start with this one. Plug it into a >2A USB phone charger.
  • The batteries are changed by lifting the R-Pi-Zero deck a bit (held by friction). When inserting the new it should be a bit more towards the back to balance the CF2.0. You can hold the small "ears" to check if it is balanced.
  • The power button is a bit hided because of the camera and you might need a "tool" to press it. I had an idea about making a motor mount with a "flange" that would make it easier to press the button but no time. For regular use, the button is probably not needed and you can plug/unplug the power cable instead. There are spare propellers and propeller guards in there if needed. There are also another set of propellers that are a bit more efficient but less trust and makes a much higher sound. You could try these if you like.
  • The parts for the CF2.0 is also there if you would like to convert it back to that.
  • I'm not sure the frame support is needed and it might be a bit in the way of the camera. You could remove this when you are more confident in things are functioning.
  • When you develop on the R-PI-Zero you could power it directly using USB or power the CF2.0 using USB. Also there is no micro-SD in it now.
  • The Flow deck doesn't work well above ~1.2m so when scripting make sure to keep it below that. Also make sure to have good lightning (not spot lightning which casts shadows) and a feature rich surface.
