Electronic

Step 1: Switch Connection

Connect the cable connector to the switch, which has two red wires.

• First, connect the DC Jack Female red wire to the cable connector.
• Take the second red wire from the cable connector and connect it to the 12V terminal on the Main PCB board.

Step 2: BMS Connections

• Connect the BMS 4-pin female connector to the battery 4-pin male connector.
• Secure the BMS P- terminal to the 12V terminal on the Main PCB board.

Step 3: Motor Connections

• Connect the left motor 4-pin connector to the left 4-pin port on the Main PCB board.
• Connect the right motor 4-pin connector to the right 4-pin port on the Main PCB board.

Step 4: LiDAR Connections

• Connect the LiDAR cable to the RP LiDAR USB adapter.

• Attach the aluminium mount securely.

• Connect a USB-C cable as follows:

  • USB-C end → RP LiDAR USB adapter
  • USB end → Raspberry Pi

Step 5: Amplifier Connections

• Connect the amplifier DC jack to the amplifier.
• Connect DC jack red and black wires → Splitter IN.
• Connect Splitter OUT → Main PCB 12V power supply.

Step 6: Speaker Connections

From the four amplifier wires:

• Wire with black line → Negative (-)
• Wire without black line → Positive (+)

Connect all four wires securely to the speaker cable connector.

Step 7: Charging Module

• Connect charging module + / - wires → Splitter OUT.
• Connect USB-C cable from charging module → Raspberry Pi.

Step 8: Raspberry Pi 2-Pin Female Header

• Connect the 2-pin female header to the UART 4-pin male connector on the Main PCB.
• Connect the other end to Raspberry Pi Pins 4 and 5.

Step 9: RGB LED Matrix Connection

• Connect the matrix light connector to the Matrix Light 4-pin female port on the Main PCB.
• Connect the other end to the Matrix Light 4-pin male header.

Step 10: Push Button Connection

Connect the push button 4-pin female connector to the Main PCB 4-pin male connector labeled Switch.

Step 11: Battery Connection

• The DC jack positive wire and BMS P- wire are connected to a nylon connector.

• Connect this nylon connector to the battery terminals, ensuring correct polarity:

  • Positive → Positive
  • Negative → Negative

Step 12: Servo Connections

Connect the servo cables to the Main PCB board by following the labeled servo port designations.

The electronic assembly is now complete.
