For the maveric board electronics, see <...>\MAVRIC\Electronics\Maveric32_autopilot\Rev4.1.1\Board_Assembly411.pdf which is a clone from this github.

  • Solder the 2mm short connector (Male on the motor phases - Female on the Speed controller phases)

  • Solder the Male 3.5mm gold connectors on the speed controller power-lines

  • Cut one Female connector of the Y connector

  • Solder the JST red connector

  • Cut the carbon rods and strips respectively to 49cm and 21.5cm long.

  • Sand the extremity of each carbon parts (to ease the slicing of 3D parts in)

  • Slice the central connection part along the rods

  • Center this part compare to the rod extremity

  • Slice the speed controller holders

  • Slice the motor holders so that the lower rod motor holder is aligned with the upper rod motor holder

  • Slice the carbon strips into the motor holders

  • Adjust the same distance between each rod extremity and motor holder (around 7.5cm)

  • Gently screw in and out one screw in all battery rack holders, to ease the next steps

  • Put the first layer of foam on the battery rack holder

  • Place the carbon rods on top, to have a X-shape Quadcopter.

  • Put the second layer of foam

  • Place the central part (with the autopilot not screwed in)

  • Screws them together, gently. Otherwise you will brake the battery rack holders !!!

  • Screw the motors on

  • Fix the speed controller using a cir-clip

  • Connect the motor phases with the speed controller phases

  • Connect the speed controller power-lines with the Y connector (red-red & black-black)

  • Place the Y connector on the bottom right part of the central part (not to disturb magnetometers which are on the left part of the autopilot)

  • Make the speed controller signal wiring going through the hole at each corner of the central part.

  • Place the satellite receiver in its slot on the central part.

  • Before going further, you should have calibrated your autopilot. If not first check the calibration part

  • Screw the autopilot on the central part, leaving the speed controller wiring going out from each corner.

  • Place the GPS

We are almost done

Plug the motors in the autopilot’s motor-plug (1: back-left, 2:front-left, 3:front-right and 4 back-right) Plug the satellite receiver in the autopilot. Plug the GPS signal in the autopilot. Plug the JST connector in the autopilot Last minute check Power on the remote Plug a battery in the Y connector Arm the motors, they should turn: Front-left clock-wise Front-right counter-clock-wise Back-right clock-wise Back-left counter- clock-wise If the motors don’t turn in the correct direction: Unplug the battery Unplug the two phases of that motor Swap them together Check again

Electronic plugs

The back of the drone is where the receiver(satellite) is placed

  • The back left ESC must be plugged in the place 1 (triplet of pin)
  • The front left ESC in 2
  • The front right ESC in 3
  • The back right ESC in 4
  • The GPS in GPS plug
  • The emitter in DC1
  • The ultrasonic sensor in I2C4
