Extremely fast brushless controller version V3 for our MikroKopter
IMPORTANT: Use FlightCtrl Firmware V2.02 (or greater), otherwise read the instructions in the wiki !
The board is tested and programmed (including bootloader)
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 with appropriate cooling
current limiting and temperature limiting
Active freewheeling -> less power loss
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

General Notice
The electronic components must be protected from moisture and humidity. When operating under such special conditions a corresponding (removable) protective coating must be used.

Note: The BL-Ctrl 3.0 controller is specifically designed and optimized for our motors. For maximum stability of the MikroKopter setpoints are set almost instantaneously on the motor. If other motors (especially larger power classes) are used with this controller, this fast change of setpoints can easily lead to very high peak currents, which bring the BL-Ctrl control to the limit or an overload. This is no fault of BL-Ctrl3.0 controller, but a systemic property. If you use other motors, this means: motors, that we are not selling, there is no warranty - use on your own risk.
