Hardware for Servo Mounts

Use the following hardware to attach the servo mounts to the back plate.

  • 8x M2.5 x 10mm
  • 8x M2.5 hex nuts

Install Servo Mounts 

Insert one of the M2.5 x 10mm long screws through a mounting hole on the back plate.

Place the servo mount over the mounting hole and line it up with the slotted tabs.

Ensure the servo mount is in the correct orientation – Reference the image for best placement.

Secure Servo Mounts

While holding the servo mount in place, insert and fasten an M2.5 hex nuts onto the thread of the screw.

Finger tighten the hex nuts and proceed to install all four screws and nuts.

Use a screw driver to tighten fasten the hex nuts to the screws.

Secured Servo Mount

Ensure the heads of the screws are facing towards the wearers back. This minimizes discomfort on the wearer. 

Secured Servos

Repeat the installation process for the second servo.

Double check the orientation of the two servos are correct and mirrored.

Ensure all of the hex nuts are tightly fastened to each of the screws.

Hardware for PCB Mount

Use the following hardware for the PCB Mount.

  • 4x M2.5 x 6mm FF standoffs
  • 4x M2.5 x 12mm screws
  • 8x M2.5 x 6mm screws
  • 4x M2.5 hex nuts

Secure PowerBoost to PCB Mount

Insert 2x M2.5 x 6mm screws through the mounting holes on the PowerBoost 1000C.

Place the PowerBoost 100C over the center mounting holes on the PCB Mount.

Insert and fasten 2x M2.5 hex nuts onto the threads of the screws on the bottom of the PCB.

Optionally install an additional 2x M2.5 x 6mm screws to the mounting holes on the back end of the PowerBoost 100C.

The mounting holes on the back end of the PowerBoost 1000C will need to be tapped in order to install M2.5 screws.

Hardware for PCB Mount

Use the following hardware to secure the PCB mount to the back plate.

  • 4x M2.5 x 10mm screws
  • 4x M2.5 x 6mm FF standoffs

Install PCB Mount to Back Plate

Line up the mounting holes on the PCB mount with the mounting holes on the back plate. 

Insert an M2.5 x 10mm long screws through one of the mounting holes on the back plate.

Place the PCB mount onto the thread of the screw.

Install PCB Standoffs

While holding PCB mount in place install an M2.5 x 6mm FF standoff on to the thread of the screw.

Repeat this process for the remaining standoffs and screws.

Secured PCB Mount

Check the standoffs on the PCB mount are tightly fastened and secured

The USB port from the PowerBoost 1000C should be pointing down to allow access for recharging the battery.

Reconnect Battery to PowerBoost

Plug in the battery to the JST port on the PowerBoost 1000C.

Reconnect PowerBoost to Servo FeatherWing

Insert the voltage and ground wires from the PowerBoost 1000C to the voltage and ground pins on the Servo FeatherWing screw block terminal.

Use screw driver to fasten and secure the wires to the screw block terminal.

Install Doubler FeatherWing to PCB Mount

Place the Doubler FeatherWing onto the PCB Mount.

Line up the mounting holes on the Doubler FeatherWing with the standoffs on the PCB Mount.

Insert and fasten M2.5 x 6mm screws to secure the Doubler FeatherWing to the PCB Mount.

Install Feather and Servo FeatherWing

Install the Feather M4 and Servo FeatherWing to the Doubler FeatherWing.

Connect Servos to Servo FeatherWing

Plug in the connectors from the servos to channel 0 and 1 on the Servo FeatherWing.

Install Battery to Back Plate

Slide the 2200mAh battery into the battery holder through the side of the clip.

Adjust the battery so it's centered with the battery holder and back plate.

Connect Potentiometer with Switch

Plug in the 2-pin and 3-pin JST connectors from the potentiometer with switch to the JST connectors on the Doubler FeatherWing.

Final Build Circuit Test

Use the switch from the potentiometer to turn on and test the circuit.
