5 🔌 Connect Wires

"Everything is connected." 🤝
5.1 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.
Observe the wiring pattern on the board
The index number of the joint servo has no corresponding relationship with the PWM pin number on the main board. You don't even need to read the pin numbers on the PCB board.


Although the BiBoard has only 12 pins, the joint index numbers are configured in the same order as the NyBoard. The connection between the joint servo and the pin is shown in the figure below:

Wire direction

The black wire (GND wire) should be closer to the board.

Inserts the infrared receiver under the back plate so that the sensor can expose to the outside.
Make sure that the wires go into the body, bypass the columns, then plug into the servo pins. Arrange the wires so they don't get in between the servo plugs and the body frame. NyBoard should be leveled on the four standoffs. Use four M2x8 self-tapping screws to fix the NyBoard.
