9. Everything Teensy 3.6

In this section we are adding the headers to the Teensy 3.6. This can be a very tedious step and requires much patience and fine motor skills. These additional headers are used to expand the available input/output pins that we need for all the functionality of Bowie. In this section, you will need the Teensy 3.6, and the various headers that go with it.

There is a way to get a very basic Bowie going with only the Teensy 3.2. This will be documented in the future.

1.


Gather all the headers necessary and the micro sd card. The headers needed are 24 pins, 24 pins, 5 pins, 5 pins, 5 pins, and also 2 rows of 4 pins, 5 pins, and 3 pins.

2.


Start first by adding solder to the pad #50.

3.


Add the 2 row 5 pin header to the area where solder to the pad was just added. Align it as good as possible.

4.


Once aligned properly, add solder to the remaining pads to secure the header in place. Remember to reflow the initial pad as well.

5.


Next, repeat the process for the next header. Add solder to pad #53.

6.


Add the 2 row 3 pin header to the area where solder to the pad was just added.

Once aligned properly, add solder to the remaining pads to secure the header in place. Remember to reflow the initial pad as well.

7.


Next, repeat the process for the next header. Add solder to pad #57.

8.


Add the 2 row 4 pin header to the area where solder to the pad was just added.

9.


Once aligned properly, add solder to the remaining pads to secure the header in place. Remember to reflow the initial pad as well.

10.


Here’s what that set of headers looks like when soldered.

11.


Add the M headers as indicated in the photo. There will be 3x 5 pins.

One of the headers will need one of the pins removed, as there is no hole for the piece to go through.

12.


Apply painters tape to keep the headers in place. Flip the board.

13.


Start first by applying solder to one pad on the headers. This can be used to reflow and manually re-position the header in case it moved while flipping. It’s important the headers are flush and perpendicular to the board.

14.


Now solder the remainder of the pads. Then flip the board.

15.


Insert 2x 24 pins along the edge of the Teensy 3.6.

16.


Apply painters tape to keep the headers in place. Flip the board.

17.


Start first by applying solder to one pad on the headers. This can be used to reflow and manually re-position the header in case it moved while flipping. It’s important the headers are flush and perpendicular to the board.

18.


Solder the first row of headers.

19.


Solder the second row of headers.

20.


Here’s what the headers look like when complete.

21.


Here’s the reverse side of the board when the headers are complete.

22.


Obtain the Bowie Brain Board with all the progress on it. Align the Teensy 3.6 headers properly. Gently squeeze it to be inserted into the board.

23.


Here is what the side view looks like. It is OK if there are small gaps like this.

24.


Here is what the angled view looks like. Again, it is OK if there are small gaps like this, as long as the connection is being made.

25.


Here is a closer view of the front.

26.


Here is a closer view of the end.

27.


Here it is, completely inserted into the board.
