Connector saver
In the event of a crash, it can happen that your LiPo battery becomes detached from your drone. The force of that happening means the battery mass, at the impact speed, is often focused at the point the connector is attached to the PDB. The result being that the PDB breaks or snaps. The connector saver prevents that from happening. Sitting between the PDB and battery connector, it dampens the force on the PDB, allowing the battery connector to separate, saving the PDB in the process.
 
PDB soft mount
Hard mounting involves attaching motors or other electronic components directly to your drone frame. For example, the motor rests on top of the frame arm and then screws are attached, from the other side of the arm, to hold the motor in place.
Soft mounting is where some form of cushioned material is placed between, for example, the motor and the frame. Vibrations from the motor are then dampened. Likewise, soft mounting an FC or stack, means any vibrations from the frame are equally dampened.
 
Some of the benefits of soft mounting are as follows:
 
Your quad flies smoother
It allows higher PID tunes, and easier PID tuning
Your motors run cooler
Video noise is reduced because mechanical vibrations can be translated into electrical noise
 
FC bobbins
These M3 5x5mm bobbins allow you to separate the different boards that form your stack. In-built cushioning dampens any electrical noise, which makes for a smoother cleaner flight.

CL Racing F4sFC v1.4
The F4S is the upgraded version of the original F4 from CL Racing and designed by Cheng Lin. Armattan have worked closely with Cheng on the development of this board and trust it explicity to deliver the best performance with their drones.
It is designed to be simpler to use with many features integrated into the board. This is an all-in-one flight controller for quadcopters with integrated PDB, OSD, buzzer and SD card slot for logging your flights. The layout of this AIO allows for lovely clean builds with ESC solder pads on the top and XT60 pads on the bottom. VTX and cam pads are also on top.
 
PDB
Armattan's Mini Power Distribution Board V3 (Mini PDB V3)
This PDB is used with many frames and comes with the Chameleon frame. As such, it is a general purpose PDB, which Armattan were selling long before the Chameleon was created.
 
There is a marked place to mount your XT60 connector; hard mounted or by incorporating the connector saver. This PDB is designed for and great with X frames. It also comes with both 5V and 12V linear voltage regulators.
