Use 3DR 915 mHz with Quadrino Nano

Hi,

I’ve followed your guide as to the pin removal to connect the two devices mentioned, but the 3DR failed to receive power upon connecting a battery to the Quadrino. Further investigation revealed that the voltage being applied to the 3DR was -5v, i.e. the voltage was being applied in the direction opposite to what was indicated by the wires. Should I flip the ground and +5v wires?

Thanks

Are you trying to connect the Radio modules to the Quadrino nano ?
If you can post some pictures of your wiring here, that would help diagnose the issue.

Yep, that’s what I’m doing…

Here’s a set of photos:

The second and third last pins (on the 3DR side) are not connected to the quadrino. All the rest are.

Thanks again for your help.

Accordint to the Quadrino Nano wiring diagram, you have all the pins reversed.
Note that this image is the Bottom view of the board.
