Connectors and pinout
This section gives an overview of the location and pinout of the different ports on RDDRONE-FMUK66.
Dronecode connectors and cable standard
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.
Two different cables with JST-GH connector.
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.
RDDRONE-FMUK66 Rev. C connectors
RDDRONE-FMUK66 Rev. C uses the new 10 pin connector for the Holybro GPS module. That GPS module incorporates the arming button and LED, as well as the beeper and an RGB high intensity LED.

Servorail on the bottom of the FMU. It has a BEC input and PWM outputs.
Connector pinout
Each connector has its own page with a pinout table and (a part of) the schematic of the connector. Some pages also include additional information relevant to the exposed interfaces. The connector specific pages are listed under this page.
RDDRONE-FMUK66 Rev. B connectors
Note that Rev. B prototype boards are deprecated and no longer supported. Information here is for reference only.
The pictures below give an overview of all connectors (and LEDs) on the RDDRONE-FMUK66 Rev. B. Most of the labels in the pictures are the same as the labels on the PCB itself.
