BL-controller

The BL-Ctrl was designed especially for Mikrokopter.

http://gallery.mikrokopter.de/main.php/v/tech/CIMG8293_Regler.JPG.html

Compared to common brushless controllers, the BL-Ctrl provides a fast data bus (i2c) to the FC and switches very fast to new target values. Common brushless controllers cannot be used.

The BL-Ctrls are adressed from 1-4(5+6) via jumpers (soldered).

Adress selection

Each motor requires a defined adress. That's why adresses from 1-6 are assigned.

http://gallery.mikrokopter.de/main.php/v/tech/Hexa.bmp.html

With a BL-Ctrl V1.2, motor adresses can be set by a jumper (soldered).
