• esp32 or other microcontroller
• 3.3v to 5v level shifter (only for boards that run at 3.3v like the esp32)

For holding clicker in place

• 1x m2x2x3.2 heat set threaded insert
• 1x m2x16mm screw
• 1x m3 washer

For Servo Mounting

• 2x m2x4x3.2 heat set threaded inserts
• 2x m2x6mm screws
• 2x m2 washers

For Assembly

• 4x m2.5x3.5x4 heat set threaded inserts
• 2x m2.5x6mm screw
• 2x m2.5x16
• 4x m2.5 washers
