# Complete the wiring

## For this section you will need:

### Printed Parts

- 1 Pi stand

### Electronic Components

- 1 Raspberry Pi
- 1 Raspberry Pi Power Supply
- 1 Sangaboard - If you cannot get a Sangaboard try building compatible arduino nano circuit

### Mechanical Components

- 2 M3 nut
- 2 M3x10 cap head screws
- 4 No 2 6.5mm self tapping screws

## Assembly video

## Step 1: Connect the Raspberry Pi

- Take the Pi stand you printed earlier and push the Raspberry Pi into place so the connectors show through the holes.
- Secure the Raspberry Pi in place with two self tapping screws
- Insert the ribbon cable from the optics module into the camera port of the Rasberry Pi, ensuring the contacts are on the opposite side from the clasp.

## Step 2: Connect the Sangaboard

- Mount the Sangaboard onto the Raspberry Pi GPIO pins, ensuring that the ribbon cable goes through the slot.
- Secure the Sangaboard in place with two self tapping screws
- Push the motor cables into their labelled connectors. Make sure the motor from the correct axis on the microscope goes to the correct port.

## Step 3: Connect the LED to the Sangaboard

- Insert the 2-pin male connector into the 4x2 way female header on the Sangaboard.
- If you are not using a Sangaboard v4, you can also connect the LED to the Raspberry Pi

## Step 4: Mount the electronics drawer

- Place an M3 nut into the slot just inside the hole in the front of the microscope base.
- Place another M3 nut into the slot above the Sangaboard power connector on the Pi stand.
- Slide the Pi stand into the microscope base making sure not to pinch any wires.
- Hold the Pi stand in place with two M3x10 cap head screws which should screw into the two nuts.

To power up your microscope you will need a power supply.
