Perma Proto

The Servo Boss is built on a perma proto board for long-term stability. Alternately, you can build it on a breadboard.

Power Jack

Solder the power jack as shown, then wire the center pin to the power rail and sleeve pin to ground.

Encoder Prep

Bend the outer legs as shown -- these are used for mechanically securing the encoders in PCBs, but there aren't holes for this in the perma proto (or breadboard).

Encoder Soldering

Solder the five encoder pins (per encoder) as shown.

Fancy Servo Headers

If you want extra fancy header pins for your servos you're in the right spot! Long header pins plus color coded plastic nubs do the trick so you can easily differentiate between power, ground, and signal.

Press the long header pins' plastic spacers down with pliers (and the pins on a hard surface), then extricate colored spacers from some donor pins.

Slide the colored spacers over the long header pins as shown, black-red-yellow ordered.

Solder Servo Pins

Place the servo header pins on the board as shown and solder them in place.

Feather Headers

Next solder in socket headers for the Feather. Since we're using the Reverse TFT Feather it is "face down" compared to typical Feather mounting.

Ground Wiring

Trim lengths of black hook-up wire to fit the ground runs from each component shown.

Servo Header Power

Solder two red wires to the center pins of the servo headers so they connect to the power rail that'll be fed by the external 5V DC power supply or battery pack.

Servo Signal Wires

Next wire the two servo signal pins to D10 and D11 respectively.

Rotary Encoder Wiring

Solder the two encoder pulse pins to their associated Feather input pins, A1/A2 and A4/A5.

Push Encoder Button Wiring

Wire the two push encoder button pins to D12 and D13.

Enable Switch

Solder the slide switch in place as shown, running the center pin to ground and the left pin to the En pin on the Feather -- this will turn the Feather on and off.
