Description

Power board with 8 integrated speed controllers BL-Ctrl v3.0.

This is the new extremely fast brushless controllers version 3.0 for MikroKopter.

All the electronic components are soldered.
The board is tested and programmed (including the bootloader) .

The new BL-Ctrl v3.0 can even be used by people flying with low-end flight stabilization systems foreseen to drive speed controllers produced in the model/toy world, working only on PPM/PWM. Even for these non-professional systems, the BL-Ctrl v3.0 will improve the flight stability and power consumption. There is nothing to configure in order to used the BL-Ctrl v3.0 in PPM mode. You just need to connect the board with the servo outputs coming from the PPM flight stabilization system.

These speed controllers work perfectly with all of our AltiGator and OnyxStar motors.


Technical specifications

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 30A (per controller) with appropriate cooling and tested up to 120A (in total for the whole board)
  • 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
  • Video

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 -> Like for the blinking LEDs 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

Interface:

  • Multiple interfaces for 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 (e.i.current limit, temperature limit, ...)
  • Two status LEDs (OK and Error )
  • Addressing by jumper  addresses from 1 to 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 the Flight-Ctrl

Dimensions:

  • Hole: 3mm
  • Weight: (approx.) 90 gr
  • Dimensions (W x H x L): approx 130mm x 28mm (without capacitors) x 130mm


Scope of delivery

  • 1 SMD preassembled, programmed and tested board with 8 ESCs
  • Lipo Power cable (open ends)
  • 1-line cable for LED output control

Notes

  • The BL-Ctrl 3.0 controller is specifically designed and optimized for MikroKopter 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 not a fault of BL-Ctrl3.0 controller, but a systemic property. Please consider carefully whether a different motor is suitable.
