Double Quadro V3 - Cool Redundance

8 ESCs on two boards (for Oktos) with heat sink! Extremely fast brushless controllers version V3 for our MikroKopter.
Version with second databus for redundance operation
IMPORTANT: Use FlightCtrl Firmware V2.02 (or higher), otherwise read the instructions in the wiki !

The board is tested and programmed (including bootloader)
FlightCtrl, NaviCtrl, MKGPS and RC-Empfänger (see photo) are NOT included!

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) and 240A (all together) 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
• Video

Redundance

• Operation with one ore two FlightControls possible
• all 8-BL-Controllers with additional second databus (UART)
• Two Lipo connection cables
• Connection of a secondary FlightControl via 3-line Molex cable

Other Features

• Integrated Buzzer
• 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

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 (OK and Error )
• Adressable by loder-jumpers (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

mechanical data

• hole: 3mm
• Dimensions (W x H ): see documention in the Wiki
• weight: ca. 260g

delivery

• 2 SMD preassembled, programmed and tested boards already mounted and soldered
• Lipo Power cable (open ends)
• 1-line cable for LED output 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.
