# Connecting 4 in 1 ESCs
|
|
|
|
## 4 in 1 ESC circuit board pin-out
|
|
|
|
Appropriate phase wires and their control signal (Fig. 1b) are marked with the same color (Fig. 1a).
|
|
|
|
For example, orange color -> bottom-right motor -> S1 - orange wire.
|
|

|
## Pixracer flight controller pin-out
|
|
|
|
Fig. 2a shows the pin-out of the terminal strip:
|
|
|
|
* **SIGNAL** — ESC connection. Every pin has its own signal. Pins 5 and 6 can receive a PWM signal (for example, a servo may be connected).
|
|
* **GND** is the ground of the flight controller. A common bus on all GND pins (marked in black).
|
|
* 1, 2, 3, 4 are ports for connecting ESCs.
|
|
* 1, 2 are ports for expanding the output PWM signal (can be setup in QGroundControl, can also can be used to control the hexacopter).
|
|
|
|
Fig. 2b shows motor numbering of the Pixracer flight controller.
|
|
|
|
* The arrow is the flight controller orientation.
|
|
* Black M3, M4 are the motors that rotate clockwise.
|
|
* Red M1, M2 are the motors that rotate counter-clockwise.
|

## Picture of the connection, based on the current orientation of the 4 in 1 ESC board
|
|
|
|
Using Fig. 1a, 1b, 2a, 2b, map its own control signal to each motor, and connect in accordance with the Pixracer motor numbering order.
|
|
|
|
For example, motor M3 that rotates counter-clockwise (top left corner) is controlled by signal S4 (green wire). It is connected to port 3.
