+Power Modules provide a regulated power supply for the flight controller, along with information about battery voltage and current.
 The voltage/current information is used to determine the consumed power, and to hence 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: [Safety > Low Battery Failsafe](../config/safety.md#low-battery-failsafe).

+# Sky-Drones SmartAP PDB
+
+[SmartAP PDB](https://sky-drones.com/power/smartap-pdb.html) (Power Distribution Board) is used to simplify the distribution of power from one or more batteries to ESCs (motors), flight controller, and other peripherals.
+It also acts as a [power module](../power_module/README.md), enabling battery voltage and current measurements.
+SmartAP PDB makes connecting high-power lines easier and much more reliable.

+## Wiring / Pinout
+
+SmartAP Power Distribution Board pinout diagram is shown below.
+
+![SmartAP PDB](../../assets/hardware/power_module/sky-drones_smartap-pdb/smartap-pdb-pinout.png)
+
+The two big pads are intended for the main battery connection.
+Up to two independent batteries can be connected using the thick wires (e.g. 8-10 AWG) to be able to handle high current loads and higher total capacity.
+Up to 12 ESCs can be connected using the 6 smaller pads on top, bottom, left and right sides.
+
+## Voltage and current sensors
+
+SmartAP PDB has integrated voltage and current sensors.
+The current sensor is located on the bottom side of the PDB.
