On the back of your OT-2, there are some electronics that are normally concealed by a black cover.
If you're working with Opentrons Support to troubleshoot a problem, we might ask you to remove the cover and expose the electronics. This article explains how to do this.
Instructions for OT-2
Allen key set provided with your robot (specifically, the 2.5mm hex driver)
Before beginning to remove the electronics cover
Make sure your OT-2 is turned off before you begin.
1. Remove the top window
First, remove the top window. Unscrew the 4 window screws, slide the window, and then lift it off.
2. Unscrew the back screws
Next, find the vent on the back, upper portion of the robot. With your 2.5mm hex driver, remove the nine screws shown below to open up the electronics enclosure cover. Note that some of the screws will be shorter than the others.
3. Remove the plastic cover
Finally, reach inside the robot and pull off the black plastic cover.
4. Electronics layout
You have successfully exposed the rear electronics! Looking through the front of the robot, you should see the exposed electronics:
The black central routing board (left).
The green Raspberry Pi (right).
A bunch of cables.
