Circuit Diagram
The diagram below provides a visual reference for wiring of the components. This diagrams was created using the software package Fritzing.
Adafruit Library for Fritzing
It is easy to use Adafruit's Fritzing parts library to create circuit diagrams for your projects. Download the library or just grab individual parts. Get the library and parts from GitHub - Adafruit Fritzing Parts.
Feathers & Tripler Feather
The Feather M4, Motor FeatherWing and mini TFT with joystick FeatherWing get installed to the Tripler FeatherWing via Headers. This makes it easy to swap PCBs and features lots of extra pins for wiring additional components. The circuit diagram only shows the PCB that require wired connections.
Stepper Motor
The bipolar NEMA-17 stepper motor features 4-wired connections that can be connected via screw block terminals on the MotorFeatherWing. Connections can be made to either the Motor 1 or Motor 2 ports, just make sure the connections are reflected in the code.
Power Supply
The Feather M4 is powered via 400mAh lipo battery. The Motor FeatherWing is powered separately with a 12V - 8x AA battery pack for providing enough voltage to power the stepper motor. If you'd like, the Motor FeatherWing can also be powered via a 12v wall adapter.
Slide Switches
A slide switch is connected to the Feather M4 via the pins on the prototyping area. To keep the Feather modular (easy to remove from the Tripler FeatherWing), a JST extension cable is wired in-line with the switch. This allows the battery to be turn off and on.
The 12v battery pack features a built-in slide switch.
