Power distribution board

The Hexa distributor supllies all 6 BL-Ctrls with power and connects the i2c bus for communication.

The BL-controllers are mounted in the fitted slots and connected with cable bridges.

/!\ The TOP ist marked by a + (plus).

Arrangement of the BL-Ctrls

The BL-Ctrls are arranged as shown here.

/!\ The microcontrollers of the Bl_Ctrl are on the TOP

Here you already see the colors of the motor cables.

If the holes of the riggers are on the right side of the rigers, please use this connection: old connection

LED Driver circuit

Three driver circuits to drive the LED bars are already integrated in the distribution board.

The circuit to drive the LED is realized by one Transistor and one Resistor.

  • BC807-25 Transistor -> 0,5A, 2N 2907A -> 1A (any other PNP-Transistor would be okay)

  • SMD 0805 Resistor 10kOhm.

Connection to the FC

The LED control signal comes from SV2 and is programmable by software: Link

Outputs (SV2 upper connector) at the FlightCtrl. The shift is a ground potential!
