SmartAP PDB (Power Distribution Board) is used for batteries and ESC connection. The board has integrated voltage and current sensors, buzzers, and 5V and 12V outputs.
The SmartAP PDB pinout diagram is shown below. The larger pads in the rear side are intended for the main battery connection. Up to 4 independent batteries can be connected using the thick wires (e.g. 8-10 AWG). The thick wires are essential to be able to handle high current loads. Both top and bottom, and left and right sides have pads for a ESC power supply connection. Therefore, up to 12 ESCs can be connected.
Soldered Power Distribution Board should look as follows:
SmartAP PRO autopilot is capable of receiving power directly from the main battery, therefore, specially dedicated solder terminals can be used. If you require the autopilot to receive the current sensor (integrated in PDB) readings, simply connect the
CURRENT signals of the PDB using a standard cable to the flight controller.
SmartAP MAX gets its power and voltage / current readings from the PDB using a standard 6-pin cable with Molex PicoBlade connectors. Simply connect the cable to the
PWR connector of the autopilot.
SmartAP PDB has an integrated electromagnetic buzzer (sounder) which is used for audio notifications, alerting users to the system status. Simply connect the
GND signals of the flight controller to
GND signals of the PDB.
SmartAP PDB has integrated voltage and current sensors. The current sensor is located on the bottom side of the PDB. For the correct scale / offset configuration, please contact us now and we'd be happy to help!
