Insert a 12-pin and 16-pin strip of male headers onto the bottom of the Feather. These will need to be soldered to the pins on the Feather.
A breadboard can be used to help keep the header pins nice and straight while soldering. The header pins are press into the breadboard.
Install Female Headers
Insert a 12-pin and 16-pin female headers into the male header pins respectively. The female headers will need to be soldered to the Perma-Proto PCB.
Install Headers to Perma-Proto
Place the headers onto the perma-proto PCB with the USB port close to the edge. Mounting tack can be used to temporarily secure the headers in place while soldering. Place a couple of pieces along side the headers and perma-proto PCB.
Apply solder to the pins on the bottom of the PCB. A panavise can help keep the PCB in place while solder. All of the holes are thru-plated and feature a nice gold finish so you won't get any oxidation.
Once all of the pins are soldered up we can remove the mounting tack. Be sure to inspect your solder joints and check to see all of the pins have enough solder.
Install Perma-Proto PCB
Place the PCB over the built-in standoffs. Insert the PCB at an angle to fit under one of the mounting tabs. Press down to snap fit into place. Fit wiring in between the snaps.
Install Case Frame
Place the case over the bottom cover and snap fit the edges together. The side with the notches are used to pass wires through.
