Checkpoint#

Verify the wiring is correct#

Visually inspect the drone#

Verify the following:

  • All red wires connected to the PDB are connected to positive (+) pads

  • All black wires connected to the PDB are connected to negative (-) pads

  • The wires on the INPUT side - NOT the OUTPUT side - of the BEC are soldered to the PDB

  • For the battery monitor lead: the red wire is connected to a positive (+) pad while the brown wire is connected to a negative (-) pad

Attention

Do a connectivity check on the PDB.

Verify there is:

  • a short between any positive (+) pad and any other positive (+) pad

  • a short between any negative (-) pad and any other negative (-) pad

  • no short between any positive (+) pad and any negative (-) pad

Do a DC voltage check on the PDB.#

Warning

Perform the voltage check only if the connectivity check passed.

Plug in a 12V battery and verify there is:

  • ~0V between any positive (+) pad and any other positive (+) pad

  • ~0V between any negative (-) pad and any other negative (-) pad

  • ~12V between any positive (+) pad and any negative (-) pad.

Note

If the battery is X volts instead of 12 volts (e.g. 10), then the multimeter will show X volts instead of 12 volts.

ESC check#

Warning

only if the DC voltage check passed (in the previous section), perform the ESC check.

Re-connect the battery to your drone.

Verify the following:

  • The PDB board lights up.

  • Each ESC emits a noise (it does so by performing a slight rotation, so you should also notice some subtle movements of each motor)
