Then Included A Mounting Position For The <A Rel="Nofollow" Href="Https://Www.Banggood.Com/5Pcs-5V-Stepper-Motor-With-Uln2003-Driver-Board-Dupont-Cable-For-Arduino-P-1210595.Html?P=M2281119547370201802">Uln2003 Driver Board</A>. With The Mount Created A Matching Jig Was Made To Help Facilitate The Wiring And Fettling Of The Boards And Motor Without Swearing Down The House. I Initially Went Over The Underside Of The Uln2003 Trimmed All The Protruding Pins And Removed The Breakout Pins. The 10Uf Capacitor Was Mounted Directly To The Digispark 5V Output And Then The Same Outputs Were Wired To The Uln2003 Power Pins. The Stepper Motor Wires Were Shortened To Make The Whole Package Neater. If Like Me You Soldered The Boards Together Before Programing The Digispark (Doh!). Remove The Ic From The Driver Board As All The Inputs Feed Directly Into The Driver Chip Before Uploading The Code. The Stepper Motor Is Mounted To The Posts With 3Mmx8Mm Self Tapping Screws And The Boards Are Glued Into Place After Final Fit. Pinout For The Boards Are As Follows: 5V To + Gnd To - P1 To In1 P2 To In2 P3 To In3 P4 To In4
