Parts Overview

For a complete list of the parts needed for this build, consult the BOM. Here's a photo of everything laid out.

Step 1: Preparing the OLED displays

Before beginning the module build, you will need to modify one of the two OLED displays by desoldering a single SMD resistor that sets the OLED's I2C address, moving its position, and desoldering it into the new position. This allows the Terminal Tedium to use both OLED displays at once, since they will each have a unique I2C address.

In the example below, the resistor will be moved from the 0X78 address to the 0X7A address.

You can desolder the LED by using a soldering iron or a hot air rework station.

Step 2: Building the Pi Hat

  1. Solder Pi Hat board
    1. 2 x 20 header
    2. 1 x 10 header (optional - used to allow access to unused GPIO pins for later experimentation)
    3. 2 x 4 power headers

Step 3: Adding the OLED displays to the front panel

1. OX7A on top
2. Place 4 screws from the front of the panel, then immediately add a nut to each
3. Put the OLED in place, then add another nut to each screw and gently tighten it down

Step 4: Adding the panel mount USB cables to the front panel

1. Unscrew the 2 screws from the front panel mount on the cable
2. Position the USB panel mount, then screw the screws back in through the panel.

Step 5: Adding the Pi Hat to the Terminal Tedium's Raspberry Pi

If you're adding the Little Traverse Bay OLED to an existing Terminal Tedium module, you'll need to follow steps 1 and 2 below. If you are building the Little Traverse Bay OLED along with building a new Terminal Tedium module, you should pick up at step 3 as you are building your Terminal Tedium.

  1. Remove the Pi from the Terminal Tedium

  1. Remove the front panel from the Terminal Tedium

  1. Next, you will add the Pi Hat to the Terminal Tedium board.

You will need to add an appropriate number of standoffs to ensure that the Pi Hat and Pi are physically supported. In the example shown below, several standoffs were used to ensure proper height. This distance may vary depending on the length of headers used.

Step 6: Connect the Terminal Tedium to the Little Traverse Bay OLED module

Add the jumper cables to connect each OLED to the Pi Hat. IMPORTANT: You will need to carefully look at both the Pi Hat and the OLED boards to make sure each jumper cable goes to the correct location. There are 4 individual connections: 3.3V (also shown as VCC), GND, SCL, and SDA. These may be arranged in different orders on the Pi Hat compared to the OLED boards, so check this carefully.
