= Differences to BL-Ctrl V1.1 =
 * Visually no difference to BL-Ctrl 1.1
 * PCB comes now with '''4-layer '''
 * Better heat dissipation of the FET's and the Shunts
 * Transistors T1, T2, T3 are replaced now by transistors with built-in resistors
 * Less sensitive to moisture <<BR>>

= Choosing the address =
On the V1.2 the motor address is set by a solder jumper on the board.

{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=73036&g2_serialNumber=4}}

It is as follows:

{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=134733&g2_serialNumber=2}}

Here you can see the addresses and positions of the motor controls and also the direction of rotation of the assigned propeller: <<BR>>

= Software =

Depending how many motors you will use on your copter you need for the upper addresses of the BL-Ctrl's a different software. This can be downloaded here:

= Assignment of the terminal =
On the pre-assembled BL-Ctrl V1.2 you need to solder the enclosed Elko:

{{attachment:BL-Ctrl_V1.2/Bl-Ctrl_v1_1.jpg}}

It is advisable to bend the capacitor by 90° so that it fit parallel to the outer side of the board.

Further you can see on the picture how to connect the I2C-Bus-Wires and the power supply.

<<BR>>

/!\ The controller is still sensitive to moisture and should be shrink wrapped with shrink tubing! For details see also BrushlessCtrl and water landing.

= Flying with 4S LiPo =
It is also possible and the same as with the BL-Ctrl V.1.1 to fly the MK with four-cell !Lipo's. See also [[4S-LiPos]].

Here you need to adjust the wirering in that way that the BL-Ctrl are hooked up directly to the power supply and __not__ over the switch of the Flight-Ctrl. That is necessary because the switch is not designed for those current and starting flashes coming with the high voltage.

Please note: In version 1.2 for T1-3 the part PDTC143 with integrated base resistor is used. The base resistors R3, R6 and R9 need to be changed through a low-resistance resistor, i.e. 100 Ohm.

##= Assembly layout =
##Top-side (Version 1.2):

##LED1 = Green, LED2 = Red, NA- NB- NC- = IRFR1205 or IPD03N03LB or IRLR7843<<BR>>
##'''__INFO:__''' The resistor '''R11''' is 680 Ohm and not like on the picture 4,7 KOhm!

##NA+ NB+ NC+ = IRFR5305 or FDD6637

= Troubleshooting =

If the BL-Ctrl have a fault, you can see this e.g. on the flashing red LED on the BL-Ctrl.<<BR>><<BR>>

How to find and fix a fault on this BL-Ctrl you can see here: [[BL-Ctrl_Fehlerbeseitigung|Troubleshooting]]
