Mini Power Brick

Airbot Systems Power modules provide a regulated power supply for the flight controller, along with informations about battery voltage and current consumption.

INTRO :

Airbot Systems Mini power Bricks encapsulate a high quality switch voltage regulator, that can support up to 12S voltage and 3A continuous power out. It has been developped to be as compact as possible and can be installed in any kind of UAV.
The Mini power bricks integrates built in voltage and current sensing. The voltage & current informations are used to determine the consumed power, and to estimate remaining battery capacity. This in turn allows the flight controller to provide failsafe warnings and other actions in the event of low power.

INSTALLATION :

The Airbot Systems Mini power brick should be installed like on the diagram below
Note : To avoid any damage on the power supplies and grant the reliability, we highly recommand to use anti-spark battery power connector on the power source ( like Amass XT90-S )

SPECIFICATIONS :

Overall dimensions : 44*27*17,6mm Mounting holes diameter : M3 Mounting holes distance : 38mm Weight : 31g (including wires) Power supply max voltage input : 12S Power supply max current output : 3A Power supply max peak current output : 4A (<few sec) Voltage sensing : Up to 12S Current sensing : 100A/200A (depends on version)
5V3 Power Supply : If used to provide over 2A continuously, we highly recommend to use an active cooling in order to limit heat. Current Sensor : In a normal use we recommend to not exceed 60%-70% of the current sensor range current capability (60/70A continuous for the 100A version)

Setup parameters

Use your favorite software to change the following parameters in your flight controller, and get the sensors working. We recommand to use Mission Planner.
