1 Version "Cool"

YOu can get the Double Quadro 2XL - Combi also as Version Cool with heatsink:

1/18
Shoplink: Doppel Quadro V3 - Cool

INFO for soldering on the Doppel Quadro V3 - Cool

The Doppel Quadro V3 - Cool has glued heatsink on the FET's. The glue becomes liquid again at

temperatures> 175°C.

When you (maybe to long) soldering the motor leads, the glue may liquefy and loosen the heatsink on the

FET.

If a heat sink has come loose, it can remain on the liquefied adhesive. This is firmly back after ~3 minutes and

final strength after about 60 minutes.

2 Double Quadro V3 - Combi

2.1 power

• voltage : 10 to 30V -> 3 -7S Lipo

6 -layer PCB for optimal heat dissipation . 70u copper layers make the entire circuit board to the heat

sink .

• 

• current: up to 60A (per BL-Unit / Peak) and 240A (all together / Peak) with appropriate cooling

• current limiting and temperature limiting

• Active freewheeling -> less power loss

2.2 Fast response with speed control

rapid acceleration and braking of the propeller. Active and seamless braking gives the speed precisely

and quickly on the new setpoint .

• 

• return energy to the lipo when braking. Seamless transition from acceleration to braking

• significantly faster control with speed control

2.3 Other Features

• Integrated 12V voltage regulator for external LED-Supply

• Switchable LED output -> LEDs can flash in case of undervoltage

• Adjustable motor timing in several steps of 13-28° - compatible with the most common BL motors

• Adjustable switching frequency ( 10kHz - 20kHz )

• PPM to 500 Hz with simultaneous I2C - bus operation for telemetry and data logging

• Integrated 12V stabilization for LED lighting and other 12V appliances

• Switchable outputs for lighting -> ZB The blinking lights at low voltage

• Software adjustable direction of rotation

• Adjustable current and temperature limits

• Adjustable start-PWM

• Silent Start: test tone at startup can be disabled

2.4 Interface

• various interfaces for setpoint input ( I2C, PPM ( 500Hz ) , serial)

Integrated current measurement measurement of the actual current and the used capacity on the

Mikrokopter control

• 

• voltage and temperature measurement with data transmission to the ground station and data logging

• 11-bit resolution (2048 steps )

• various feedback to the MikroKopter-FlightCtrl ( blocked motor , power limiting , etc. )

• extented configuration options (eg current limit , temperature limit , ...)

• two LEDs per BL-Ctrl (OK and Error )

• all BLCs are already adressed (address 1-8)

• I2C bus access possible in PPM mode - for data logging and telemetry in PPM mode

• status messages are transmitted to the FC ( engine blocks , Current, Self-test error ...)

• current measurement up to 75A per controller

• Convenient configuration of the BL controller via FC

=> Color "Black", "Gray", "Blue" shows how to connect the cables of the MK motors. =>

You can either solder the cables on the top or the bottom side.

♦ 

• 

Addressing

=> If you purchase the double-quadro unit in the shop, the BL-Ctrls are already addressed

from 1-8. The addresses are marked on the boards

=> General adressing the BL-Ctrl (See Address)

♦ 

• 

LiPo-Voltege outputs (for low currents up to 3A)

♦ => plus (LiPo)

• 

Optional

♦ => Second Recom -> You can add a second voltage converter (for example 5V)

Slave

◊ => Not used

♦ 

• 

Buzzer

♦ => The buzzer is directly connected to the Board

4 Connection Double Quadro

The double quadro consists of two quadro boards. They are connected by solder wires in these points:

• I2C (SCL)

• I2C (SDA)

• Buzz (Summer +)

• LiPo +

• LiPo -

5 Addressing

The addressing of the individual BL-Ctrl in the distribution board is done by a solder jumper:

Here you can see how to set the solder jumper:

5.1 Motor address + connection

Here you can see how the address for each motor should be set at the upper and lower board:

(If you buy the "Double Quadro 2XL - Combi" at the MK-Shop the addresses are set like you see here)

INFO:

The cables for the motors on the lower PCB (Adr. 2, 4, 6, 8) can also be soldered on the bottom of the lower

PCB!

You can use the "normal" Okto mixer that you find in the KopterTool.

6 Settings

IMPORTANT: To change the Settings of the BL-Ctrl V3.0 you need a Software version since V2.02a

(KopterTool, FlightCtrl, NaviCtrl)!

Normally you have not to change the settings! If you have to to it you can do it like described:

• open KopterTool

• press button "Strg" on your keyboard and hold it down.

• Then "click" "Settings" in the KopterTool.

Now you will see the window of the BL-Ctrl V3.0.

INFO: only if you "click" and activate the single settings there you can change them.

8 Error codes

The BL V3 performs a selftest during startup (test-tone). In case of an error, these are the blink codes:

• 1 "1" = Shortcut between A+ and B-

• 2 "2" = Shortcut between B+ and C-

• 3 "3" = Shortcut between C+ and A-

• 4 "E" = A doesn't go to high

• 5 "F" = B doesn't go to high

• 6 "G" = B doesn't go to high

• 7 "H" = A doesn't go to low

• 8 "I" = B doesn't go to low

• 9 "J" = C doesn't go to low

• 10 "K" = Overcurrent when switching to low

• 11 "L" = Overcurrent when switching to high

• 12 "Q" = Cross-circuit between low and high

• 15 overcurrent while starting the motor

10 FAQ

10.1 Motor connection

The motors can be connected either on the top-side or on the bottom-side. You can ignore the small

(pre-)soldered points on the top-side.

10.2 Buzzer

The buzzer is directly soldered into the Board

10.3 Adressing

If you purchase the double-quadro unit in the shop, the BL-Ctrls are already adressed from 1-8. The adresses

are marked on the boards

10.4 What is the gray 1-line cable for?
