# NyBoard

## Servo wiring

Connect the wires of servos to the NyBoard servo pins as below. They follow a circular symmetry. Notice the skipped indexes between the head and leg servos (1\~7). They are reserved for our future robots with more joints.

{% hint style="danger" %}
The index number of the joint servo has **no corresponding relationship** with the PWM PIN on the main board. **You should not read the PINs on the PCB board during assembly.** 
{% endhint %}

### Wire direction

Please ensure the black wire (or the darkest wire - ground wire) is closest to the board.

Insert the infrared receiver under the back plate so the sensor can be exposed to the outside.

Ensure the wires go into the body, bypass the columns, and plug into the servo pins. Arrange the wires so they don't get between the servo plugs and the body frame. NyBoard should fit flat on the four standoffs. (It is OK for the board to have a minor bend caused by the chassis.) Use four M2x8 self-tapping screws to fix the NyBoard.

Ensure all the servos are connected to the correct sockets on the circuit board in the proper orientation.
