Headers for Perma Proto and QT Py

Get the male and female stacking headers ready for soldering. Make the following adjustments to the strips of header by trimming them with flush snips.

• 2x 1x7 female stacking headers
• 2x 1x7 male headers

Install Headers to QT Py

Solder the two 1x7 strips of male headers to the QT Py. Use a breadboard to help keep them sturdy while soldering. 

Installing Stacking Headers 

To make assembly easier, install the two female stacking headers onto the male headers of the QT Py.

Install QT Py to Perma Proto

Place the stacking headers onto the Perma-Proto board so it's at the edge of the PCB.

Solder the stacking header pins to the Perma-Proto.

Install Lipo Charger BFF Add-on

Place the Lipo Charger BFF onto the back side of the Perma-Proto PCB with the JST port facing the QT Py's USB.

Solder the Lipo Charger BFF in place and trim the excess pins short when complete.

Solder Ground Wires

Install six 10 ohm resistors to six of the available ground pins on the Perma-Proto.

Create a set of six ground wires to be about 13cm (5.12in) in length.

Solder each ground wire to the 10 ohm resistors.

Solder Anode Wires

Flip the Perma-Proto PCB for soldering wires.

Create a set of six wires (23cm (9in) long) for connecting to the LED noodles anode pin. 

Solder each wire to the following pins on the BFF: SCK, MISO, MOSI, A1, A2, A3

Solder a wire to connect the ground pins to the ground pin on the BFF.

Solder the three wires from the 3-pin molex cable to pin A0, TX and a ground pin on the BFF.

Soldered Perma-Proto

Double check all of the wires and pins have been properly soldered. Add pieces of heat shrink tubing (or tape) to keep the wires bundled together.
