Raspberry Pi and Sangaboard base
This base fits both the Raspberry Pi (Models B+, 2, 3B, 3B+, 4B) and the Sangaboard v2, with holes for the wires and connections and space for an optics module to move.
Warning: Make sure your SD card is flashed with the OS and software and inserted into your Raspberry Pi.

Method
Base stabilisation
You may wish to add rubber feet to your Raspberry Pi & Sangaboard base for stability.
Alternatively, you could drill holes in the bottom of the base to attach it to an optical bench.
Add Raspberry Pi
Connect the camera ribbon cable and LED to the Raspberry Pi.
Place the Raspberry Pi into the bottom of the case. Screw the four M2.5x20mm standoffs through the holes of the Raspberry Pi (hand tight or using small pliers or SW5 nut driver, being careful not to over-tighten) and into the base. You may find it easier to tap the holes with M2.5 screws before.
Add Sangaboard
Place the Sangaboard on top of the standoffs, making sure the cables from the Raspberry Pi have space. Screw the M2.5x7mm screws using a M2 screwdriver through the holes of the Sangaboard into the standoffs. You might find it easier to attach all four loosely, then tighten them together. Be careful not to over-tighten these screws.
Plug in motors
Plug in the motors. Two of the motor cables can enter though the window in the side of the case and the other one can enter through the reflection illumination cutout. The correct order to plug in the motors can be seen here:
(For other motor controllers: a = x, b = y, c = z)
Connect the Sangaboard
The Sangaboard connects to the Raspberry Pi by USB cable. There is a special window for the USB cable to pass through.
Attach the camera ribbon cable
Connect the ribbon cable to the camera module.
Put microscope into base
The microscope fits snuggly into the base. Make sure the motor cables and LED cable exit through the gap and don't get trapped.
Attach external components
There are windows around base to connect external components. On the side there is space for USB power to the Raspberry Pi and Sangaboard and HDMI.
At the back there is space for USB components (for example: keyboard, mouse, memory stick) and ethernet.
