Product Description

UAV's are getting bigger and its commonplace to use multiple LiPo's in parallel to increase the flight time, add redundancy or reduce the current draw from the LiPo packs.
The Sensor Hub X8 was developed to connect up to 8 main batteries in parallel. Which would give an total current range of 8x 200A = 1600A !
If this is still not enough, then install 2x Hub X8 and combine them with an Hub X2, which gives you the possibility to connect up to 16 main batteries in parallel.

Also you don't have to connect all 8 sensors. Any number from 1 to 8 is possible, as the Hub X8 checks during booting the connected sensors and deactivate any unused sensor input.

The Sensor Hub X8, is able to collect the current of up to 8 current sensors and pass the summarised current to the FC.

Included:

1 x Sensor Hub X8
8 x Connection cable to current sensor PC-100 or PC-200 / L = 200mm
1 x Alarm output cable and external Reset / Restart / L = 200 

Required parts:

1 x Power-Cube 1, Power-Cube 2, Power-Cube 3 or Power-Cube 4
1 x Sensor Hub X8
3-8 x Current sensor PC-100 or PC-200

Optional parts:

3-8 x CFK enclosure for PC current sensor
3-8 x 2x 15cm 8AWG upgrade for PC-200 sensor
 

Installation Instructions:

The Sensor Hub X8 can be either installed via double side tape, or screwed down to the main frame, by removing the 4 bottom M3 screws and drilling holes into the frame. Then reinstall the screws trough the frame. -> The original screws will be too short, so please replace them with longer ones according your frame thickness.

Connection to external equipment:

 
 

1. Connection to Power-Cube:

 
Please connect here the cable (To P-C current sensor) which comes together with the Power-Cube.
This connection carries the power supply for the Hub X8 as well as the connected current sensors.
The voltage is 4.95-5.05V and the max. current should not exceed 0.5A.

The current draw of the Hub X8 (with active OLED) is 50mA, plus 8x 15mA (current sensors) = 170mA (0.17A)
So even if we connect 2pcs X8 with 16 current sensors, plus an Hub X2 (15mA), we're still below the 0.5A.
(2 x 0.17A) + 0.015A = 0.335A

2. Sensor connectors:

 

Please connect here any of PC-xxx sensors. However, all sensors must be of the same current rating !

If you use less than 8 sensors, then it doesn't matter where you connect the sensors.

For more details, please check Pos. (9).

  • The 8 cables to connect the PC-xxx sensor boards, come together with the Hub X8 (L=200mm)
  • Only PC-xxx sensors can be used. The Hub X8 is not compatible with HS-xxx-xx sensors ! 

If all 8 possible sensors are installed, but you want to fly your UAV with only 4 LiPo's, then you can deactivate the unused current sensors, by either disconnecting them from the Hub X8, or install a switch into the GND wire of the sensor board.

REM: Please do not install the switch into the + 5V or I-out cable !

If the sensor is disconnected, or the GND wire is switched off, then the Hub X8 will deactivate the sensor input during boot up or restart.

3. Reset / Restart:

In case of any alarm (over current or under current), then the you can perform an reset, by either re-powering the Hub X8, or press the reset switch for a short time.
If you press the reset switch longer than 2 seconds, then the Hub X8 will restart. This is helpful if you deactivate installed sensors after switching on the system.
It is possible to install an external reset / restart switch (not included), the necessary 5p cable with connector is included.
2x red for external switch + 3x white for alarm relays output.
4. Status LED:
RED = During startup / Any alarm is active and the alarm relays is ON / If the Reset - Restart switch is pressed.
GREEN = After boot up and all connected sensor are initialized / No active alarm
5. Alarm Out:
Pin 3 = P -> The middle contact of the relays.
Pin 4 = NO (normal open)
Pin 5 = NC (normal closed)
Any power LED or buzzer can be connected here, but the max. current should not exceed 1A !
The necessary 5p cable with connector is included. -> 2x red for external switch + 3x white for alarm relays output.
 

6. External LCD / OLED display:


If the Hub X8 is installed in a place where the display is no more visible, then you can connect here a standard 2x16 LCD display (4 bit data bus), but please do not use any LCD display's with back LED light, as these light's can draw easily more than 200mA and the supplied power from the Power-Cube might be not enough.
You also can install an 2x16 / OLED display. The current draw of these displays are minimal (30mA). -> Internal and External display can be active.
REM: External OLED displays with CFK cover and reset switch might be available soon.

Please check Pos. (7), for how activate / deactivate the internal and external display.

8. I2C connector:

 

9. Sensor status indicator:

The numbers 1 to 8 are for the current sensors and the symbol above indicates the status.
_  = No sensor connected or sensor deactivated -> See Pos. (2)
II  = Sensor connected and current is within average.
L  = The current of this sensor is at least 25% lower than the average current of the other sensors -> Alarm relay active
H  = The current of this sensor is at least 25% higher than the average current of the other sensors -> Alarm relay active
10. Sensor indicator:
Here it is displayed how many current sensors are connected/active and the current range of the individual sensor.
11. Current display:
The display will show the summarized current of all sensors, based on the standard Amp/Volt settings -> See Pos. (12)
12. Current output and setup MissionPlanner:
The output voltage from the Sensor Hub X8 is always optimized to be 0.0-3.3V from 0A to full current on all sensors. Doesn't matter how many sensors are connected/active. This ensures, that we always use the full range of the FC analog input, to get the most accurate current readings as well as capacity consumption calculation.
For example:  4 x 100A Sensors = 0.0V @ 0A and 3.3V @ 400A    -> Amp/Volt value = 120
                       5 x 200A Sensors = 0.0V @ 0A and 3.3V @ 1000A  -> Amp/Volt value = 300
                       8 x 200A Sensors = 0.0V @ 0A and 3.3V @ 1600A  -> Amp/Volt value = 480

Please follow the procedure here to setup the correct Amp/Volt value: http://ardupilot.org/copter/docs/common-mauch-power-modules.html
