This section gives an overview of the pinout for various ports on the RDDRONE-FMUK66.
Most interfaces on the RDDRONE-FMUK66 use the JST-GH connectors as specified in the Dronecode Autopilot Connector Standard. The PWM interface uses "standard" RC hobby servo connections. These PWM connectors are 3 pins spaced 0.100" apart.
The male JST-GH connector has a clip on top. As described in the Dronecode standard, the first (leftmost) wire is usually the positive voltage. In some cables this wire is red. The last (rightmost) wire is ground. The wires in between carry different kinds of signals, depending on the function.
The following pictures give an overview of all connectors (and LED indicators) on the RDDRONE-FMUK66. Most of the labels in the pictures are the same as the labels on the PCB itself. Below you can find further details about the functions of the different ports.
