Build A 290 Mini FPV Racing Hexacopter

Step 6: Connecting The CC3D Mini Atom

The CC3D Mini Atom Flight Controller

There is no difference between the functionality of the CC3D flight controller and the CC3D Mini Atom. The only difference between the two is the size, the Mini Atom (above photo) is definitely mini and only half the size of the Open Pilot CC3D controller.

Before we mount the Mini Atom into our hexacopter frame, for the sake of clarity, let's go over the connections for the FlySky FS-R6B 6 channel receiver. Of all the input connections, the most important is to put the three wire ( white|red|black) on Channel 1 of the radio receiver with the white wire going on the signal row of pins. After that, it doesn't really matter which of the other wires go on the other five channels because the Radio Wizard in the Open Pilot Ground Station will actually configure the rest. However, we'll list the connections that we made:

  • Channel 1: white|red|black with the white wire on the signal pin
  • Channel 2: blue wire with the wire on the signal pin
  • Channel 3: chartreuse wire with the wire on the signal pin
  • Channel 4: green wire with the wire on the signal pin
  • Channel 5: yellow wire with the wire on the signal pin
  • Channel 6: black wire with the wire on the signal pin
  • BAT: the row of pins identifies as BAT should have no wires connected to it

For the time being, you can disconnect the radio receiver and then mount the Mini Atom on top of the power distribution board using some double sided tape. Note: As with most flight controllers (if not all), there is a directional arrow (below photo) which must point to the front of your hexacopter racer.
