Eagle based schematic for an Arduino compatible microcontroller optimized to run an electronic dividing head using a stepper motor using Chuck Fellow's electronic divider head sketch.
This schematic permits the use of a power source anywhere from ~5.25V to 36V up to 5A. The design permits the user a fairly wide choice in the selection of stepper motor.
I'm also uploading a eagle pcb board layout file which features headers for mounting Pololu's A4988 stepper motor driver carrier, a separate lighted keypad, and either 20x4 or 16x2 LCD displays, an external LED indicator, side panel mounted dc power jack, power switch, and cooling fan. The board is designed to fit within a compact enclosure to protect the controller from the shop environment.
NOTE: right click the file name and select "save as" to save the code properly.
