Top Side

Molex-Connector to connect to power distribution board

1 - Molex Connector

• Connections from top to bottom:
  1 - Ground (GND FC and Buzzer)
  2 - + Buzzer
  3 - I2C Bus (D)
  4 - I2C Bus (C)
  5 - +12V
  
  

• suitable connector for the Molex cable

• suitable Molex cable

If you are using this new connection you will be unable to install a power switch for your Flight Controller. The Mikrokopter will then get turned on by connecting your Lipo battery. (All MK with more than 4 engines do that anyways).

Bottom Side

1 - 10pin connector for MK-USB or NaviCtrl connection
2 - Pressure Sensor (cut out of sensor connector points to the right)
3 - 6pin connector for servo 2 and Servo 3
4 - 6pin connector for servo 4 and servo 5
5 - DC/DC voltage regulator 5v Recom for Flight Controller
6 - DC/DC voltage regulator 5v Recom for servos
7 - 6pin connector for NaviCtrl
8 - 6pin connector for servo 1 and switchable J16/J17 connectors
9 - I2C connector (C/D) for BL Controllers
10 - JET (If you are using the Jeti Satellite receiver you will have to bridge these two connectors)
11 - 5pin connector (5V, GND, 3,3V, RX,TX)

• Connection for Jeti receiver:

  • Connect PPM cable to #13, bridge the 2 connectors on #10 and connect RX
    

  Connection for Spektrum Satellite::

  • Connect the orange Receiver cable on 3,3V, black to G and gray to RX
    

12 - connection for the buzzer (BUZ-/BUZ+)
13 - Connection for PPM receiver (GN-brown, +5V-red, PPM-orange)
14 - Ground (GND) connection for the Flight Controller
15 - Positive (+) connection for the Flight Controller (if a power switch is being used)
16 - Positive (+) connection for the Flight Controller (without a power switch)

Connections

(FC2.1 and FC2.0 are identical except the new Molex Connector)

Connectors SV1

Connectors SV2

Upper Row (switchable outputs)

Pin1: 100mA switchable output with NON Open Collector for LED's, Programmable with MK Koptertool with J16.

Pin3: +5 Volt

Pin5: 100mA switchable output with NON Open Collector for LED's, Programmable with MK Koptertool with J17.

Lower row: Nick-Servo Output

Pin1: Servo 3 output

Pin3: +5V

Pin5: GND

Lower Row: Roll-Servo Output

Pin2: Servo 2 Output (Setting in Koptertool)

Pin4: +5V

Pin6: GND

Connectors SV4

Upper row: Servo 5

Pin1: Servo 5 output

Pin3: +5V

Pin5: GND

Lower Row: Servo 4

Pin2: Servo 4 output

Pin4: +5V

Pin6: GND

Receiver Connection

Please note, that you have to choose the right receiver in the settings under "Channels".

Standard PPM-Receiver

Examples:

• DSL4TOP (35/40MHz)

• R6107SP Futaba 2,4GHz

Connection:

Spektrum Satellite Receiver

The 3,3V power connection for the satellite receiver is on the bottom side of the Flight Controller.

Connection:

Also see: Spektrum

Jeti Satellite Receiver

The external diode is already integrated into the FC2.1 circuit and therefore will not have to get soldered.

Connection:

Also see: JetiDuplex

HoTT Receiver

Since Software version V0.86

The HoTT receiver will also connected on the PPM and RX pads of the FlightCtrl. To send the telemetry a solder bridge on "JET" is needed.
More informations about the HoTT-System you can find here: HoTT

Connection:

Futaba S.Bus Receiver

Since Software version V0.88 / FlightCtrl V2.1

A S.Bus receiver can be connected with a signal-inverter to the FlightCtrl.
The needed Signal-Inverter you can get here: Shoplink

Connection:

Wiring Diagram

The usage of MikroKopter Software is only permitted on original MikroKopter hardware.

Hardware Changes since V2.00

• new controller with double the flash memory (ATMEGA1284P)
• Molex-connector for easy power distribution board connection
• integrated power supply for Spektrum Satellite receiver
• JET connector bridge for easy usage for JETI down-link
• Adjustable resistor for pressure sensor to accommodate 2000-3000 meters in elevation depending on weather
• resistor adjustment for I2C Pull-Ups.
• Protection diode for Buzzer
• new black color

What's included and what has changed compared with V2.0

• Pressure Sensor MPX4115A is included
• 2 power regulators (recom or similar) are included to supply your flight controller and servos with power
• power switch is NOT includes and has to get ordered separately

Other

• the boot loader for FC2.1 is not public domain and can not be read out thanks to our good friends in china.

• a AtMega1284 Prozessor with programmed bootloader is available here

• under no circumstances is it allowed to program or delete the ISP with Atmel programmers

Software Development

• For software development for the new AtMega1284 processor and you need the WinAVR-20060421 Compiler and a special Patch from H&I.

• In addition, in the makefile of the project, change the processor to "MCU = ATMEGA1284P".

Upgrade for 5S and 6S LiPo

Should a 5S or 6S Lipo be used instead of a 4S Lipo, the Recoms regulator must be replaced with an appropriate Traco DC/DC regulator.
Furthermore, all electrolytic capacitors in the input area should be exchanged with 25V-rated types.
All reconstructions of the FlightCtrl board are taken at your own risk.

• The voltage regulator must be replaced with one of a correspondingly high input voltage range (e.g. Traco TSR1-2450) as the Recoms only permits up to 18V input voltage. Costs about €9.

• All SMD capacitors in the input area should be rated to 25V. However, the Kerko - subject to availability upon placer - also only 16V. (yes, the FC is also sold as a max. 4s in the shop) If in doubt, replace.
• Exchange the large radial leaded capacitor "C55" for a 330μF/25V type.
