# Hardware Connectivity
Communication Architecture
The Jetson has two main ways of communicating with the flight stack and payloads. The Jetson is connected via ethernet to both the ethernet port at the top of the drone, the 8 pin ethernet port at the bottom of the drone, and the radio. These channels are for the Jetson and drone controller communication, payload communication, and developer access through SSH. The Jetson is also connected to the flight controller through serial UART, which is the channel for [mavlink communication](https://docs.flybydev.com/quickstart/nvidia-orin-nx#mavlink).
## Payloads
The F-11 can carry up to 6lb payloads. Payloads can be powered and controlled through the readily available external ports and connectors available on the drone.
#### Mounting Points
There are 22 total mounting points, all of which use M3 screws. 10 are on the top of the drone, and 12 are on the bottom. The bottom points have a depth of 5mm, while the top have a depth of 8mm.
#### External Peripherals
There are three XT30 connectors on the bottom of the drone. The first XT30 connector is 12V at 9 amps, the second is VBAT (36-50.4V) at 9 amps and the final is 28V at 4 amps.
\
The main I/O access points on the drone are the standard ethernet port located at the top of the drone, two peripheral USB 3.0 (type A) ports, one 10-pin gimbal control port, and one 8-pin ethernet port on the bottom of the drone.
\[Note: Do not block the power button and air vents when mounting payloads. The power button is the 18mm diameter round structure on the lid of the drone towards the back of the housing.]
